Nuclear level density of fission products 133-137Xe and 135-138Ba is estimated using a shell-model-based method. The shell-model Hamiltonian is constructed by combining the monopole-based universal interaction, VMU, and the M3Y type spin-orbit interaction. The model space is truncated based on the binding energy of each configuration estimated from the monopole interaction. The calculated level densities are in good agreement with available experimental data, and the effects of spin-orbit and tensor forces on the nuclear level density and shell effects in the spin distribution are discussed.
Nuclear level density is important for evaluating nuclear reaction processes, but its microscopic investigation is not frequently performed. The present work applies a recently developed shell-model-based method to estimate the level density of fission products 133-137Xe and 135-138Ba. The monopole-based universal interaction, VMU, and the M3Y type spin-orbit interaction are combined to construct the shell-model Hamiltonian. The model space is truncated based on the binding energy of each configuration, estimated from the monopole interaction. The calculated level densities of 133-137Xe and 135-138Ba are in good agreement with available experimental data. The effects of spin-orbit and tensor forces on the nuclear level density and the shell effects in the spin distribution are discussed.
