The study of secondary gamma-transitions from 155Gd(n,γ)155Gd reaction for different filtered neutron beam energies

The theoretical and experimental estimations of the possibility to obtain the information about the excited level spins from secondary capture γ-ray studies for different quasimonoenergetic neutron beam energies were fulfilled. The preliminary experimental results confirm the dependence of the secondary γ-ray intensities ratios, taken for the different neutron energies, from the spin of decaying level, and the possibility to describe this effect using the γ-cascade model.
