K- - meson production in proton-nucleus collisions
Sibirtsev, A.; Büscher, M.; Müller, H.; Schneidereit, C.
K- - meson production in proton-nucleus interactions at projectile energies up to 15 GeV is studied. As a first step the available data on K- - meson production in pp interactions are compared with different parametrizations and results of model calculations. Because of considerable uncertainties in the current descriptions of the energy dependence of the elementary K- cross section a new parametrization is suggested. Experimental data on K- production in pA collisions are analyzed in the framework of the Rossendorf-Collision and folding models. Satisfactory descriptions of the momentum spectra at forward angles are achieved. From an analysis of the A dependence it can be concluded that K- mesons are well suided to investigate final-state interactions for particles interacting strongly with the residual nucleus. Furthermore, we propose experimental studies on K- production close to threshold. Such measurements are particularly sensitive to contributions from secondary processes or from multi-nucleon interactions.

Plans for investigations of subthreshold K+ production in p+A collisions
Schult, O. W. B.; Sistemich, K.; Koptev, V.; Müller, H.; Cassing, W.; Jarczyk, L.; Komarov, V. I.; Sibirtsev, A.; Ernst, J.; Santo, R.; Nioradze, M.; Kulikov, A. V.; Hardt, A.; Dshemuchadse, S.; Leege, K.-W.; u. a.
We plan to investigate sub-threshold K+ production in proton bombardment of atomic nuclei in order to study the reaction mechanism through a measurement of the double differential cross section and of K+ p and K+ d coincides. The status of the theoretical studies is summarized, and the spectrometer to be installed in the COSY ring is briefly described.

In-Beam Study of 109Sn
Käubler, L.; Prade, H.; Reif, J.; Schwengner, R.; Winter, G.; Grawe, H.; Heese, J.; Kluge, H.; Maier, K. H.; Schubart, R.; Spohr, K.
In-beam spectroscopic investigations of 109Sn have been performed
using the reactions 55Mn(58Ni,3pn) and 106Cd(alpha,n)
with E58Ni= 240 MeV and Ealpha=23 MeV, respectively.
An extended level scheme of 109Sn is presemted showing high-spin
states up to Ex ca. 8 MeV with Jpi=(41/2+).
The problem of the 109Sn ground state has been solved identifying
a 12.8 keV transition deexciting the 7/2+ state to the 5/2+
g.s. A half-life of T1/2=7(1) ns has been measured for
the 17/2+ state at Ex=2114 keV. The experimental
data are compared with the predictions of shell-model calculations.

The proton g9/2 isomer in the N=50 nucleus 87Rb and M2 transition rates in 85,87Rb
Käubler, L.; Protochristov, C.; Michailova, M.; Reif, J.; Andrejtscheff, W.; Funke, L.; Kostova, L.; Prade, H.; Schwengner, R.; Winter, G.
ow-lying states of the N=50 nucleus 87Rb have been investigated
in the (alpha, alpha') reaction measuring gamma gamma- and delayed gamma-rf-coincidences.
A half-life of T1/2=6(1) ns was obtained for the level at 1578.1
keV. This experimental result confirms the 9/2+ assignement
and the proton 1g9/2 single-particle character of this state.
Experimental M2 transition strengths in 85,87Rb are compared
with predictions of the shell model and the particle-core coupling mwodel.

Their decay to the 5/2+ ground state has been observed identifying
a 12.8 keV 7/2+ -> 5/2+ transition. A half life of
T1/2=7(1) ns has been measured for the 17/2+ state
at Ex=2114 keV. The experimental data are compared with the

First Observation of the Scissors Mode in a Gamma-Soft Nucleus: The Case of 196Pt
von Brentano, P.; Eberth, J.; Enders, J.; Esser, L.; Herzberg, R.-D.; Huxel, N.; Meise, H.; von Neumann-Cosel, P.; Nicolay, N.; Pietralla, N.; Prade, H.; Reif, J.; Richter, A.; Schlegel, C.; Schwengner, R.; Skoda, S.; Thomas, H. G.; Wiedenhöver, I.; Winter, G.; Zilges, A.
A nuclear resonance fluorescence experiment with one of the newly developed
highly efficient EUROBALL cluster detectors has been performed on the gamma-soft
nucleus 196Pt. Magnetic dipole excitations were observed between
2 and 3.5 MeV excitation energiy. They are interpreted as the main fragments
of the scissors mode based on the measured excitation strengths and branching
ratios. A strong gamma decay, which we believe to be an E2 decay of the
scissors mode to the 21
+ state, is observed. It allows
an extraction of the effective boson quadrupole charges in the interacting
boson model.

Added Stiffness Relating to Small Motions of Two Concentric Cylinders Submitted to Axial Annular Incompressible Flow
Zoller, J.
Abstract
Axial incompressible, viscous flow is considered in an annular gap between two rigid cylinders. If the cylinders are displaced from their concentric positions in a certain manner, the displacement will cause reaction forces exerted by the fluid pressure. In this investigation the pressure fluctuations caused by the displacement of the structures are approximated by analytical means. Pressure fluctuations in phase with acceleration and velocity of the structure are not calculated here. Stationary flow is considered, because structural displacements are assumed to be small.

Schwankungen des Massenstroms bei Druckentlastungsvorgängen
Lucas, D.; Prasser, H.-M.
Bei der linearen Stabilitätsanalyse des Abblaseprozesses aus Druckbehältern mit zweiphasigem, aufwallendem Medium wurden Instabilitätsbereiche mit starken Massenstrompulsationen in der Abblaseleitung gefunden. Entscheidender Mechanismus ist die Rückkopplung zwischen Gemischspiegelschwankung, kritischer Ausströmrate und Druckabfallgeschwindigkeit. Für die Stabilitätsanalyse wurden analytische Modelle zur Beschreibung des bertragungsverhaltens aufgestellt. Es wurden Nyquist-Diagramme für verschiedene Parameterkombinationen untersucht und so die Instabilitätsbereiche identifiziert. Die Schwingneigung wird durch hohe Gasgehalte an der Entlastungsarmatur, eine große Verzögerungszeit (Länge der Abblaseleitung) und geringe Höhen der Schaumzone befördert.

Investigations of an externally heated storage vessel
Aszodi, A.; Liewers, P.; Krepper, E.; Prasser, H.-M.
Storage tanks for fluids are widely used industrial facilities. As a consequence of an external fire, the heat-up of the inventory may lead to the evaporation of the liquid and to release of significant quantities of dangerous gases into the environment. Experimental investigations performed in FZ-Rossendorf have shown that the liquid inventory behaves very differently depending on the mode of heating. Bottom heating leads to an irregular thermoconvective motion of the liquid, which causes good mixing, so that saturation is reached at all places inside the tank approximately at the same time. The maximum enthalpy of the liquid always remains close to the average value. If the vessel is heated from the side, a stable temperature stratification is observed leading to large temperature gradients. Evaporation can start much earlier than the average temperature reaches saturation.
In order to clarify the physical nature of the details of the heating-up and the evaporation process in simple geometrical boundary conditions a two-dimensional mathematical model was developed, which includes also evaporation and two-phase flow. The aim of the simulations was, to understand the basic phenomena observed during the experiment.
To avoid fast temperature increase at the fluid surface in the case of side wall heating, the insertion of baffle plates inside the vessel was investigated by additional calculations using the CFD-code CFX-4.

Thermal dilepton and open charm signals versus hard initial yields in heavy-ion collisions at RHIC and LHC energies
Kämpfer, B.; Pavlenko, O. P.
Abstract
The hard initial production of open charm and dileptons is compared with possible thermal signals in heavy-ion collisions at RHIC and LHC energies. Our approach is based on the perturbative QCD mini-jet mechanism of quark-gluon matter formation. The thermal dilepton signal is found to rise much stronger as compared to the hard Drell - Yan background with increasing collider energy and clearly dominates at LHC energy. Oppositely, open charm stems from initial hard production. A possible rnanifestation of gluon shadowing at RHIC and LHC energies is discussed.

Verhalten von Lagertanks bei externem Feuer
Krepper, E.; Aszodi, A.
Wenn ein zylindrischer Lagertank durch ein externes Feuer von der Seite intensiver Wärmeeinwirkung ausgesetzt ist, so setzt der Massenverlust infolge von Dampffreisetzung viel eher ein, als im Fall einer Wärmezuführung vom Behälterboden. Mittels eines vereinfachten Modells konnten die Details des Erwärmungsprozesses und die Ursachen für das unterschiedliche Verhalten in Abhängigkeit von der Art und Weise der Wärmezufuhr erklärt werden. Die ZUfuhr vom Boden führt zu einer irregulären thermischen Konvektion und damit einer guten Durchmischung des Fluids, so daß die Sättigungstemperatur an allen Punkten im Behälter nahezu gleichzeitig erreicht wird. Die maximale Enthalpie im Behälter verbleibt während der gesamten Zeit nahe dem Mittelwert. Wird der Behälter von der Seite beheizt, so bildet sich eine stabile horizontale Temperaturschichtung heraus. Die Bildung von Dampf erfolgt bereits lange bevor die mittlere Temperatur den Siedepunkt erreicht hat. Passive konstruktive Maßnahmen, wie der Einbau von Prallplatten, können die Schichtung stören, das verstärkte Aufheizen an der Oberfläche vermeiden und die Freisetzung von Dampf verzögern. Eine durchgreifende Vermischung des flüssigen Inhalts konnte jedoch nicht erreicht werden. Die genaue Gestalt und die Wirkung dieser Prallplatten hängt von der konkreten Behältergeometrie ab und läßt sich weiter optimieren.

Untersuchung von Zweiphasenströmungen gasförmig / flüssig mit Positronenemittern
Hensel, F.
Die Methode der Positronen-Emissions-Tomographie (PET, Positron Emission Tomography) wird zur Untersuchung von Zweiphasenströmungen flüssig / gasförmig angewandt. PET ist ein bildgebendes Verfahren, das für die Nuklearmedizin entwickelt wurde. Im medizinischen Bereich wird diese Technik hauptsächlich als nichtinvasives Untersuchungsverfahren für die quantitative Erfassung von Stoffwechselvorgängen in-vivo genutzt. Die hier vorgestellten Untersuchungen zur Methodik der Anwendung von Radiotracern für Strömungsuntersuchungen wurden 1994 begonnen. Das Ziel der Arbeiten war die örtlich und zeitlich aufgelöste Erfassung von Vermischungs- und Transportprozessen sowie die Messung der Dichte von zweiphasigen Medien. Zur Dichtemessung wurde die Abhängigkeit der Positronenreichweite von der Dichte des Materials ausgenutzt. Bei den entsprechenden Experimenten kam eine örtlich fixierte Positronenquelle (45Ti) zum Einsatz. Desweiteren wurden Messungen zum Stofftransport in Blasenströmungen durchgeführt, hier wurden flüssige Tracer mit dem Nuklid 18F eingesetzt.

Determination of Crack-Initiation Toughness by Impact and Dynamic Testing
Richter, H.; Böhmert, J.; Viehrig, H.-W.
The critical J-integral (Jid) can be useful as toughness parameter at initiation of stable crack growth. Under the condition of the impact bending test the critical step for evaluating of Jid is the detection of the crack initiation point on the impact load displacement curve. In this paper the crack initiation is determined by using emission of acoustic waves (AE). The experimental techniques used to evaluate Jid include both instrumented impact testing based on 300 J pendulum impact tester with a piezoelectric broadband AE sensor within the impact tup and dynamic 3 point bending loading with a servohydraulic test machine and additional AE sensors on the specimen.
Different kind of pulses of the AE signals can be observed. One of them corresponds with crack initiation. The evidence of initiation at this point was confirmed by single and multiple specimen methods.

Diphoton rates from thermalized matter resulting in ultra-relativistic heavy-ion collisions
Hentschel, M.; Kämpfer, B.; Pavlenko, O. P.; Redlich, K.; Soff, G.
Abstract
Diphoton radiation off strongly interacting matter resulting from ultrarelativistic heavy-ion collisions is estimated for SPS and RHIC conditions. At SPS emrgies tha thermal diphoton signal competes strongly with the Drell - Yan like background. For given charged-particle rapidity density a scenario with deconfinement transition predicts a larger diphoton yield than a scenario without phase transition. For RHIC energies we find that radiation from initially undersaturated (but gluon-rich) deconfined matter overwhelms the hadron gas and the Drell - Yan like diphotons in the invariant mass window 1 < M < 2.5 GeW. Due to this the so-called M1 scaling is approximately obtained and can serve as additional tsol for discriminating radiation from quark-gluon matter.

Radium Sorption on Sandy and Clayey Sediments of the Upper Saxon Elbe River Valley
Baraniak, L.; Thieme, M.; Funke, H.; Bernhard, G.; Nindel, K.; Schreyer, J.; Nitsche, H.
Radium sorption from pure and slightly contaminated groundwater onto limonite-rich turonian sandstone is characterized by relatively low distribution ratios (60-180 mL/g). When contacted with mine water, the sorption was enhanced by more than 20-fold compared to the pure and contaminated groundwaters. For the typical lime marl, the strongest sorption occured from the groundwater (390-520 mL/g) and a slightly reduced sorption took place from the acidic mine water.
In addition, the radium sorption was studied as a function of the Ba2+ and SO42- concentration. The results were discussed in terms of the ion product and the solubility product. Conclusions were drawn regarding the predominant sorption mechanisms: coprecipitation, surface complexation and ion exchange.
The long-term migration behaviour in the aquifers of the south-east Saxon Elbe basin was calculated on the basis of Hadermanns' equation, considering convection, dispersion, retardation and radioactive decay.

Nanometre-sized Silver Halides Entrapped in SiO2 Matrices
Matz, W.; Pham, T.; Mücklich, A.
The formation of nanocrystals after implantation of silver
alone as well as together with the halogen ions Cl, Br, and I into a SiO2
layer of about 100 nm was studied by X-ray diffraction and transmission
electron microscopy. The co-implantation of Ag and Cl/Br results in the
formation of cubic AgX-crystals which are stable in size under annealing.
The co-implantation of Ag and I as well as single Ag implantation result
in Ag crystallites, which grow under annealing. The annealing procedure
causes a redistribution of the particles within the layer.

Pacaud, Y.; Stoemenos, J.; Brauer, G.; Yankov, R. A.; Heera, V.; Voelskow, M.; Kögler, R.; Skorupa, W.
In recent years, single crystal SiC has become an important electronic material due to its excellent physical and chemical properties. The present paper reports a study of the defect reduction and recrystallization during annealing of Ge+-implanted 6H-SiC. Implants have been performed at 200 keV with doses of 1x1014 and 1x1015 cm-2. Furnace annealing has been carried out at temperatures of 500 °C, 950 °C and 1500 °C. Three analytical techniques including Rutherford backscattering spectrometry in conjunction with channelling (RBS/C), positron annihilation spectroscopy (PAS) and cross-sectional transmission electron microscopy (XTEM) have been employed for sample characterization. It has been shown that damage removal is more complicated than in ion-implanted Si. The recrystallization of amorphized SiC layers has been found to be unsatisfactory for temperatures up to 1500 °C. The use of ionbeam-induced epitaxial crystallization (IBIEC) has been more successfull as lattice regrowth, altough still imperfect, has been observed to occur at a temperature as low as 500 °C.

A study of the blue photoluminescence emission from thermally-grown, Si+ -implanted SiO2 films after short-time annealing
Skorupa, W.; Yankov, R. A.; Rebohle, L.; Fröb, H.; Böhme, T.; Leo, K.; Tyschenko, I. E.; Kachurin, G. A.
Thermal SiO2 films have been implanted with Si+ ions using double-energy implants (200 + 100 keV) at a substrate temperature of about -20 °C to total doses in the range 1.6 x 1016 - 1.6 x 1017 cm-2 followed by short-time thermal processing, in order to form a Si nanostructure capable of yielding blue photoluminescence (PL). The intensity and the peak position of the PL band have been investigated as a function of ion dose, manner of heat treatment, anneal time and anneal temperature. For the formation
of blue PL emitting centres, optimum processing conditions in terms of excess Si concentration and overall thermal budget are mandatory. The nature of the observed blue emission is discussed.
