2021FA08 Phys.Rev. C 103, 064310 (2021) State densities of heavy nuclei in the static-path plus random-phase approximation NUCLEAR STRUCTURE 148,149,150,151,152,153,154,155Sm; 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.

2020FA02 Phys.Rev. C 101, 014607 (2020) P.Fanto, Y.Alhassid, H.A.Weidenmuller Statistical-model description of γ decay from compound-nucleus resonances NUCLEAR REACTIONS 95Mo(n, γ)96Mo*, E(γ)<10 MeV; calculated partial widths of the neutron and the γ-decay channels, and total γ-decay width distribution for all the spin-parity values of the resonances of the compound nucleus using random-matrix model with coupling to the entrance neutron channel and to a large number of nonequivalent γ channels, employing empirical parametrizations for nuclear level density (NLD) and γ strength function (γSF); deduced that Porter-Thomas distribution (PTD) described the distribution of partial widths for all the decay channels, in agreement with the statistical-model expectation, and that large fluctuations of the total γ-decay widths in experiments by 2013Ko13 could not be explained within a statistical-model description of the compound nucleus.

2019AL09 Phys.Rev. C 99, 024621 (2019) Y.Alhassid, G.F.Bertsch, P.Fanto, T.Kawano Transmission coefficients in compound-nucleus reaction theory

2018FA06 Phys.Rev. C 98, 014604 (2018) P.Fanto, G.F.Bertsch, Y.Alhassid Neutron width statistics in a realistic resonance-reaction model NUCLEAR REACTIONS 194Pt(n, n), (n, γ), E=1-14 keV; calculated neutron strength function parameter, σ(E), and reduced neutron width distributions; deduced that Porter-Thomas distribution (PTD) describes well the distribution of reduced neutron widths, and that nonstatistical interactions do not explain the experimentally observed PTD violation. Statistical model calculations combined with a realistic treatment of the neutron channel described by Gaussian orthogonal ensemble (GOE) of random-matrix theory. Comparison with experimental data.
