Re analysis of Temperature Dependent Neutron Capture Rates and Stellar \b{eta} decay Rates of 95 98Mo

TL;DR

This study reanalyzes neutron capture and stellar beta decay rates of Mo isotopes using statistical and pnQRPA models, finding neutron capture dominates over beta decay at various temperatures.

Contribution

It provides updated calculations of neutron capture and beta decay rates of Mo isotopes using advanced nuclear models, improving upon previous data.

Findings

Neutron capture rates are significantly higher than beta decay rates across temperatures.

The models show good agreement with existing experimental data for MACS.

Temperature influences the dominance of neutron capture over beta decay.

Abstract

The neutron capture rates and temperature dependent stellar beta decay rates of Mo isotopes are investigated within the framework of the statistical code (Talys v1.96) and proton neutron quasi particle random phase approximation (pnQRPA) models. The Maxwellian average cross section (MACS) and neutron capture rates for 95 98Mo(n,{\gamma}) 96 99Mo radiative capture processes are analyzed within the framework of statistical code Talys v1.96 based on the phenomenological nuclear level density (NLD) parameters and gamma strength functions (GSFs). The current model based computed data for MACS provide a good comparison with the existing measured data. The temperature dependent stellar \b{eta} decay rates of 95 98Mo are investigated at different densities within the framework of the pn-QRPA model. For the considered temperature range, the neutron capture rates were found to be higher, by orders of magnitude, than the stellar \b{eta} rates.
