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.
