State densities of heavy nuclei in the static-path plus random-phase approximation

NUCLEAR STRUCTURE ^{148,149,150,151,152,153,154,155}Sm; calculated ground-state energies, canonical entropies as function of inverse temperature, state densities as function of excitation energy using the static-path plus random-phase approximation (SPA+RPA) in the configuration-interaction (CI) shell-model framework against exact shell-model Monte Carlo (SMMC) state densities. Comparison with mean-field state densities calculated with the finite-temperature Hartree-Fock-Bogoliubov (HFB) approximation. Comparison with experimental data.
