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

The neutron capture rates and Maxwellian averaged cross sections (MACS) for 90Zr (n, ) 91Zr and 92Zr (n, ) 93Zr 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 models nuclear properties (level density and gamma-ray strength) to reproduce experimental data will allow the detailed investigation of the s process network.
