Half-lives of one-proton emitters using Effective Liquid Drop Model

The nuclei lying in the vicinity of the proton drip line are proton emitters. A systematic analysis of the half-life of one proton emitter was estimated using the Effective Liquid Drop Model. We have exploited various mass tables say AME2020, WS4+RBF, FRDM, and KTUY in evaluating the Q-values. The half-lives obtained using various mass tables are compared with experimental values. Among the theoretical mass tables, WS4 is found to have less deviation in the prediction of the half-lives of one proton emission. Alpha-decay half-lives are also estimated to determine which decay mode dominates in the selected isotopes. Geiger-Nutall plots have been plotted and the linear nature of the graph has been successfully reproduced for all the mass tables. The New Geiger-Nuttal law, which illustrates the angular momentum dependency on half-life, also reproduces the linear nature of the graph.
