Gamma Radiation Following Resonance Neutron Capture
In this publication three topics are presented describing experiments performed at the GELINA pulsed neutron source and covering different aspects of resonance neutron capture gamma-rays. The first is concerned with the study of radiative primary transitions in s-wave and p-wave resonances of Cr-53, resulting in E1 and M1 average strengths covering a rather broad energy interval (4.1 MeV to 9.7 MeV). The second deals with the role of neutron capture spectroscopy in the study of sub-barrier fission. It concentrates in particular on the intermediate structure group of U-238 fission resonances around 720 eV and tries to answer the much debated question whether its central resonance at 721.6 eV has mainly a Class II character or not. Finally, the third work describes the spin assignment of U-238 p-waves using the low level population method: these results are of interest for the parity violation (PV) measurements carried out at Los Alamos by the TRIPLE collaboration. The role of the spin determination in improving the estimate of the root mean square value of the PV matrix is briefly discussed.
