The study of the half lives alpha decay of 90 208-239 Th using semi-empirical methods

Abstract

Half lives alpha decay is the one of the most important parameters used for describing nuclear structure in nuclear dynamics; over the years, many studies have been done in this area. In this study, by using semi-empirical methods such as Viola-Seaborg (VSS), Royer, Parkhomenko and Sobiczewski (PSM), Brown, New Geiger-Nuttall (NGN), Poenaru et al. (UNIV) and Universal Decay Law (UDL), the half lives alpha decay of Thorium chain isotopes were considered and compared with the experimental data. The Viola-Seaborg method served as the best approach among the semi-empirical methods introduced above for studying Thorium chain isotopes
