Bound-state β- Decay and Its Astrophysical Significance
-
摘要: 束缚态β-衰变是一种特殊的弱相互作用衰变模式,对某些高电离态重原子的β-衰变有重要或决定性的贡献.从理论和实验两方面介绍了束缚态β-衰变研究的进展及其对恒星中的慢中子俘获过程和187Re 187Os宇宙核钟的影响.Abstract: The boundstate β- decay stands for a particular weak interaction decay mode, which has a significant or dominant contribution to the β- decays of some highly ionized heavy atoms. The progress of the theoretical and experimental studies on this decay mode, and its importance to the sprocess synthesis of heavy elements as well as the 187Re、187Os cosmochronometer are presented.
