The gamma-decay of particle-hole states in 208Pb using the Euroball Cluster detector

Neutron particle-hole states in the doubly magic nucleus ²⁰⁸Pb
were investigated using a Euroball Cluster detector and five usual HPGe
detectors at the Osiris cube spectrometer in Cologne. 126 gamma-ray transitions
with energies up to 7.2 MeV could be detected, 14 of those for the first
time. The states were excited with the ²⁰⁸Pb (p,p'gamma)²⁰⁸Pb
reaction via isobaric analogue resonances in ²⁰⁹Bi at E_p=16.5,
17, 17.45, 17.5 and 18.5 MeV and through the subcoulomb ²⁰⁷Pb(d,pgamma)²⁰⁸Pb
reaction at E_d=10 MeV. For most of the excited states assignments
for the particle and/or the hole component of the configuration could be
made, 22 of these are new.
