Investigation of ${}^{90,92}$Zr(n,γ)${}^{91,93}$Zr in the s-process nucleosynthesis

The neutron capture rates and Maxwellian-averaged cross-sections (MACS) for ${}^{90}$Zr(n,γ)${}^{91}$Zr and ${}^{92}$Zr(n,γ)${}^{93}$Zr processes have been computed within the framework of Talys v1.96. The effects of phenomenological nuclear level density (NLD) parameters and the gamma strength functions (GSFs) on Maxwellian-averaged cross-sections and neutron capture rates are examined both quantitatively and qualitatively. The present model-based computed data for MACS and reaction rates gives a good comparison with the existing literature. The fine-tuning of the statistical model's nuclear properties (level density and gamma-ray strength) to reproduce experimental data will allow the detailed investigation of the s-process network.
