Abstract

Describing the nuclear radiative strength function (RSF) at energies below the neutron separation energy (Bn) is crucial for providing reliable input in nuclear reaction and nuclear astrophysics calculations. In this study, we evaluate eight RSF models, encompassing both phenomenological and microscopic approaches, by employing them as input to calculate the neutron-capture cross-section of the 55Mn(n,γ)56Mn reaction. The obtained result is then compared with the experimental one. Our results indicate that microscopic RSF models built on the Hartree-Fock mean field theory offer good descriptions of the cross-section, with notable performance observed in the temperature-dependent Hartree-Fock-Bogoliubov (T-dependent HFB) model. Selecting such appropriate RSF models ensures reliable input for calculations related to nuclear reactions and astrophysics.
