Investigation of Proton-Capture and Stellar β-Decay Rates of 94Mo

Abstract

The radiative proton-capture of \(^{{94}}{\text{Mo}}\)(p, γ)\(^{{95}}{\text{Tc}}\) and the stellar weak rates for ⁹⁴Mo are calculated within the frameworks of the Hauser–Feshbach theory and proton–neutron quasi-particle random phase approximation (pn-QRPA) model. The radiative capture rates, utilizing both phenomenological and microscopic nuclear inputs, are constrained by the experiment based on the rms error. The fitted capture cross-sections are used to predict the thermonuclear reaction rates at various stellar densities and temperatures. Using the constrained rates, the destructive rates are calculated using a set of relative hydrogen abundances and stellar densities as suited for SNIa and SNII environments. At the same densities and temperatures, the stellar weak rates are analyzed within the framework of pn-QRPA under the deformed basis. Both the temperature-dependent stellar weak rates and the destructive rates (p, γ) are investigated at the same densities and temperatures.
