Non-Resonant Alpha-Induced Neutron-Emission: A Multi- Method Comparison Of Nuclear Reaction Rates

The precise calculation of alpha-induced neutron-emission ($α$,n) reaction rates is fundamental to understanding nucleosynthesis in diverse stellar environments. This study investigates the nuclear reaction rates for various non-resonant alpha-induced neutron-emission reactions by employing analytical, theoretical, and computational methods. We have adopted analytical expressions from existing literature, and for the computational approach, we have implemented the Monte Carlo method. To better understand the functionality and validate the established open-source Monte Carlo scripts, we also developed our own computational code and used it to test various aspects of the method. A comprehensive comparison of the reaction rates from each method is presented by plotting their dependency on temperature.
