摘要：

The study aimed to develop an empirical formula for phase space factor and nuclear matrix element to analyse two neutrino double beta decay. The present work also extended to compute phase space factor using Primakoff-Rosen approximation. Using these two formulae for phase space factors we have computed two neutrino double beta decay half lives. Comparisons of the calculated half lives with the corresponding experimental values are also done. The empirical formula predictions are found to be in good agreement with the experimental data. The empirical formula is applied to various isotopes exhibiting single beta decay and our prediction on the possibility of two neutrino double beta decay will be very useful for the future experiments.
