Abstract

The results of fully microscopic calculations for the α-decay half-lives of light α emitters close to the N=Z line are presented. The ground-state properties are calculated in the relativistic mean field (RMF) approach which reproduce the experiment well, as expected. The α-daughter nucleus potential is then calculated in the double folding model using the density dependent M3Y nucleon-nucleon interaction and the RMF nuclear density distributions. This potential in turn is used to calculate the α-decay half-lives in the WKB approximation. The results closely agree with the corresponding values obtained by using the available phenomenological expressions as well as with the experiment. The α-decay half-lives of a few Te, I, Xe, Cs, and Ba isotopes have also been predicted.
