中文摘要：

【正】 We generalize the formula of β~+-decay half-lives [Phys.Rev.C 78 (2006) 014305] to include all availabledata of nuclei far from the β-stable line. Good agreement with experimental data is obtained by taking into accountthe even-odd (e-o) effect.It is shown that the e-o effect on β~+-deeay half-life is apparent for the allowed β~+-transition,whereas it is not apparent for the first and second forbidden transitions.This demonstrates that the allowed β~+-transitionis more sensitive to the nuclear even-odd effect than the forbidden β~+-transition.The underlying physics is discussed.This formula can be used to predict the β~+-decay half-lives of the nuclei far from β-stability.It is useful to experimentalphysicists for analyzing the data of β~+-decay.
