The Gd-155(n,gamma) reactionwas measured with theDANCE gamma-ray calorimeter (consisting of 160 BaF2 scintillation detectors) at the Los Alamos Neutron Science Center. The gamma-ray energy spectra for different multiplicities were obtained for the s-wave resonances.
The shapes of these spectra were compared with simulations based on the use of the DICEBOX statistical model code. Simulations showed that the photon strength functions (PSFs) successfully describing the decay of Gd-156 are very similar to the PSFs describing the decay of previously published Gd-158 results.
It was demonstrated that the scissors mode is required not only for the ground-state transitions, but also for transitions between excited states. DOI: 10.1103/PhysRevC.87.044609
