Calculation of the total gamma-spectra of the fast neutrons capture in the isotopes 117,119Sn for the different parameters of cascade gamma-decay

TL;DR

This paper calculates gamma-spectra for neutron capture in isotopes 117 and 119Sn, highlighting the importance of nucleon Cooper pair breaking in accurately modeling cascade gamma-decay parameters.

Contribution

It introduces a method that incorporates nucleon Cooper pair breaking effects into gamma-spectra calculations for specific isotopes.

Findings

Accurate reproduction of experimental spectra requires considering Cooper pair breaking.

Different level densities and radiative strength functions significantly affect gamma-spectra.

Nucleon pairing effects are crucial for modeling cascade gamma-decay in these isotopes.

Abstract

The gamma-spectra were calculated for the set of different level densities and radiative strength functions. The sufficiently precise reproduction of the experiment is impossible without taking into account the influence of the process of the nucleons Cooper pairs breaking on any nuclei cascade gamma-decay parameters.
