Abstract
The thermonuclear reaction rates and Maxwellian-averaged cross-sections (MACS) for the \(^{84}\)Kr(n,\(\gamma\))\(^{85}\)Kr and \(^{86}\)Kr(n,\(\gamma\))\(^{87}\)Kr processes were examined using the statistical model code Talys v1.96. The effects of nuclear level densities (NLDs) on Maxwellian-averaged cross-sections and neutron capture rates are examined both quantitatively and qualitatively. The present Talys-based MACS and radiative capture rates for \(^{84}\)Kr(n,\(\gamma\))\(^{85}\)Kr and \(^{86}\)Kr(n,\(\gamma\))\(^{87}\)Kr processes agree well with the earlier reported findings. The statistical model’s nuclear properties (level density and gamma ray strength) were fine-tuned to reproduce the existing experimental nuclear data.
