Study of Interatomic Potentials in ZnS - Crystal-GRID Experiments versus ab initio Calculations

Koch, T.; Heinig, K.-H.; Jentschel, M.; Börner, H. G.

Crystal-GRID measurements have been performed with ZnS single crystals. For the first time, an asymmetric Crystal-GRID line shape could be observed. The preliminary data evaluation indicates that the reported lifetime of the 3221 keV level in 33 is too short. A value of about 60 fs has been found. Due to this ``long'' lifetime the line shape is much less structured than calculated with the reported lifetime.

Potential investigation for ZnS using Crystal-GRID high-precision gamma spectroscopy and MD computer simulations

Hauschild, T.; Heinig, K.-H.; Jentschel, M.; Börner, H. G.

Crystal-GRID is a new and complementary method for studying interatomic potentials in crystals at intermediate energies between 1 eV and 1 keV. After a neutron capture reaction a first photon emission leads to a recoil of the still excited nucleus. While moving through the crystal a second photon is emitted. When observing many recoil events a structured and Doppler broadened gamma line shape is obtained due to the anisotropic slowing down in the crystal. Experimental findings from the high-precision gamma spectrometers GAMS 4 and GAMS 5 at the ILL are compared to predictions from molecular dynamics (MD) simulations. Thereby information about the interatomic potential can be obtained. Results will be presented for ZnS single crystals, showing that the universal screened Coulomb potentials (ZBL, KrC) are not appropriate in the examined energy region. A new potential for that region will be presented.

Crystal-GRID: Current status and prospects for experimental studies of atomic collisions in solids.

Jentschel, M.; Hauschild, T.; Börner, H. G.; Heinig, K.-H.

The Doppler effect of electromagnetic radiation represents a very direct indicator to study the motion of emitting particles. In the Crystal-GRID technique one uses the ultra high resolution power of the crystal spectrometers GAMS4 and GAMS5 to measure the Doppler broadening of $\gamma$ radiation emitted from excited nuclei. Thus it represents a new nuclear probe for the direct study of atomic motion in solids at kinetic energies of several hundreds of eV.

A detailed description of the experimental technique will be given together with an overview on already performed experiments using massive single crystals
of TiO2, NaCl, Ni and Cr. In these experiments the comparison of experimental data to predictions deduced from Molecular Dynamics simulations has allowed to obtain new repulsive interatomic potentials.

The currently used double flat crystal geometry of the spectrometers has allowed to use only massive targets. Recent technical improvements of the GAMS5 spectrometer towards a double bent crystal geometry
will allow to extend the technique to studies of crystalline layers as they may result from ion implantation. The current status of the spectrometer and the expected capabilities will be presented.

Study of Interatomic Potentials in ZnS using Crystal-GRID high-precision gamma spectroscopy and MD simulations

Hauschild, T.; Jentschel, M.; Heinig, K.-H.; Börner, H. G.; Möller, W.

Crystal-GRID measurements have been performed with ZnS single crystals. A new Crystal-GRID potential could be determined by splining a Stillinger-Weber like equilibrium potential to screened Coulomb potentials. The new potential is fitted to experimental data containing information about the energy range of about 10 to 500 eV and differs significantly from the screened Coulomb potentials. The nuclear level life time of the 3221 keV level in 33S has been determined to be (48.8 +/- 0.7) fs. Furthermore the predicted asymmetry of a Crystal-GRID line shape could be observed for the first time.

Nitriding of stainless steel by low energy ion implantation - the nitriding kinetics

Parascandola, S.; Kruse, O.; Richter, E.; Möller, W.

Stainless steels are known for their excellent corrosion resistance based on a native surface oxide layer and a moderate hardness leading to short life times in applications with intensive wear. Hence, surface hardening could greatly enlarge their range of applications. However, stainless steels are considered as difficult candidates for surface hardening. Nitriding by low-energy ion implantation is a promising technique. At target temperatures of about 400°C the formation of a highly nitrogen enriched layer has been observed. This layer exhibits an increased surface hardness and a reduced wear without adversely affecting the excellent corrosion resistance.
This work focuses on the nitriding kinetics which are not well understood. Experimental data has been obtained by time and depth resolved elemental analyses using elastic recoil detection (ERD) during the nitriding process. The ERD technique has been optimised for time resolved in-situ data acquisition. Fast nitrogen diffusion, an energy and current density dependence of the thickness of the nitrogen enriched layer and an influence of the surface oxide layer have been observed. The physical origin of these phenomena will be revealed and a simple model of the nitriding process taking into account the governing physical processes, i. e. sputtering, recovering of the surface from the residual gas and diffusion in the solid, will be presented.

Nitrogen transport during plasma ion nitriding of austenitic stainless steel - the role of the native surface oxide layer

Parascandola, S.; Kruse, O.; Richter, E.; Möller, W.

Austenitic stainless steels are widely used due to their advantageous combination of properties as ductility, strength and excellent corrosion resistance. However, due to their moderate hardness they are not suited for abrasively stressed parts. Hence, the market potential of austenitic stainless steels could be greatly enhanced by a process that allows surface hardening without negatively affecting the other properties. Standard techniques as heat treatment, carburizing and conventional nitriding fail. Recently it has been shown that ion nitriding at moderate temperature is a promising candidate for surface hardening austenitic stainless steels. Surface hardness increased by factors of 4 to 5 leading to wear resistance increases by more than two orders of magnitude have been achieved without compromising the excellent corrosion resistance. It has been reported that the nitriding velocity depends on the ion energy and on the current density and that the passivating surface oxide layer of the austenitic stainless steels may play an important role. In a systematic study the influence of the surface oxide layer on the nitriding efficiency of ion nitriding austenitic stainless steel at moderate temperatures is analyzed by determining the retained nitrogen dose for fixed process times and temperatures but different oxygen partial pressures, ion current densities and ion energies. Additionally, for some selected process parameters during processing, the composition of the near surface region (down to 150nm) regarding the nitrogen, the carbon and the oxygen content is obtained by an in situ experiment.

Das typische Höroldt-Motiv findet sich wieder auf einem Walzenkrug, ebenfalls aus weißem Porzellan als Träger. Mittels Ionenstrahlanalyse an Luft gelang es am 5 MV Tandembeschleuniger des FZ Rossendorf, zerstörungsfrei aufzuklären, dass die Pigmente der Schmelzfarben auf der Vase der überlieferten "Höroldt'schen Palette" entsprechen. Im Gegensatz dazu wurde z. B. Chrom-Grün am Walzenkrug gefunden, was eindeutig auf eine Kopie hinweist.

What is the physics behind the 3He-4He anomaly?

Neubert, W.; Botvina, A. S.

We show that coalescence of nucleons emitted prior to thermalization in highly excited nuclei can explain the anomaly of kinetic energies of helium fragments. This mechanism accomplishes the statistical approach to nuclear rections formerly used to describe intermediate mass fragment production.

Keywords: Intermediate energy hadron -nucleus and nucleus-nucleus interactions; helium isotopes

Fragmentation of Be induced by 1 GeV protons

Andronenko, L. N.; Andronenko, M. N.; Gusev, Y. I.; Kotov, A. A.; Neubert, W.; Petrov, G. E.; Seliverstov, D. M.; Strakovski, I. I.; Vaishnene, L. A.; Yatsoura, V. I.; Zalite, A. Y.

Fragment yields and energy spectra of He, Li and Be isotopes have been measured in p+9Be interactions at 1 GeV incident energy at 30 deg. and 126 deg. using a two-arm
spectrometer based on Bragg chambers. The obtained yield ratio of the low abundant
8He to 8Li in the spectator momentum range is compared with published data.

Keywords: fragmentation; cross section; isotope; proton

Hydrogen and deuterium depth profiling in divertor tiles of a fusion experiment by micro-ERDA

Grambole, D.; Herrmann, F.; Behrisch, R.; Hauffe, W.

Depth profiling of light elements in the surface layer of solids by means of ERDA is limited to depths smaller than about 1 mu m. In order to measure the distributions
of hydrogen isotopes in larger depth regions such as needed for the divertor tiles from the tokamak fusion experiment ASDEX-Upgrade in the Max-Planck-Institut
fur Plasmaphysik, samples cut from the divertor tiles (about 0.6 mm tungsten on carbon) were bevelled at different angles by mechanical cutting and polishing or by
ion beam slope cutting. The mechanically cut slopes were additionally cleaned and polished by oblique incidence ion beam sputtering with target rotation to avoid
anisotropic etching.
The surface composition along the slope was measured by ERDA with the Rossendorf Nuclear Microprobe, A 10 MeV Si ion beam was focused to about 3 mu m
and scanned linearly across the slope. The hydrogen and deuterium recoils were detected by a surface barrier detector at a recoil angle of 30 degrees after passing
through a 10 mu m thick Al foil for stopping scattered primary ions. Deuterium was found at depths up to about 25 mu m and hydrogen up to 750 mu m on the
samples analysed.

Keywords: micro-ERDA; elastic recoil detection; depth profiling; hydrogen; deuterium

Fragment production in proton interactions with light nuclei

Andronenko, L. N.; Andronenko, M. N.; Seliverstov, D. M.; Neubert, W.

Isotopic yield ratios were derived from double-differential cross sections measured in p+9Be and p+12C collisions at 1 GeV. Enhanced 9He yields were found compared to heavier target nuclei.
