自发单质子放射性核半衰期数据的理论计算
Theoretical calculations on half-lives of spontaneous one-proton radioactivity
摘要
Abstract
Studying unstable nuclei beyond the nucleon drip line is an important method to study the nuclear interaction and structure in the extremely neutron-or proton-rich systems.Various nuclides beyond the proton drip line mainly decay through spontaneous one-proton emission.Using deformed Woods-Saxon potential,spin-orbit potential,and expanded Coulomb potential to construct the daughter-proton potential,the half-life data of various proton emitters are systematically calculated based on the quantum tunneling model and the microscopic Gamow state theory.By using nuclear data from different sources and comparing them with the measurements,the dependence of proton emission on decay energy and spectroscopic factors is evaluated.Additionally,based on previous observations,the half-life of the possibly lighter proton emitter in the fpg-shell below has been theoretically predicted.Our results are compiled into a comprehensive dataset of half-lives for both experimentally confirmed emitters(50＜Z＜84)and theoretically predicted emitters(30＜Z＜50),providing a useful reference for future experimental investigations related to the proton drip line.The datasets presented in this paper,including our results of calculation,are openly available at https://www.doi.org/10.57760/sciencedb.27551.关键词
