Abstract
In order to evaluate the global alpha-nucleus optical potentials used in the simulation of the astrophysical \(\gamma \)-process, the cross section measurement of the \(^{92}\)Mo(\(\alpha \),n)\(^{95}\)Ru and \(^{92}\)Mo(\(\alpha \),p)\(^{95}\)Tc reactions is in progress at MTA Atomki using the activation technique. Precise information on the half-lives of the reaction products are essential for such a measurement. The half-lives of the produced \(^{95}\)Ru and its daughter \(^{95}\)Tc are published in previous works, however with large uncertainties and ambiguous values, therefore, these values have been re-measured with high precision using \(\gamma \)-spectroscopy. Details on the experimental approach and the half-life determination are presented in this article.
