作为集体核模表现的alpha decay系统学的突变
Abrupt changes in alpha decay systematics as a manifestation of collective nuclear modes
摘要：
讨论了N=126中子壳层闭合附近$α$衰变系统的突然变化。它被解释为最终形成$α$粒子的核子聚集的突然阻碍。这是因为，如果组态空间不允许配对集体性的适当表现，则由作用于四个核子的配对模式引起的成团被抑制。
英文摘要：
An abrupt change in $α$ decay systematics around the N=126 neutron shell closure is discussed. It is explained as a sudden hindrance of the clustering of the nucleons that eventually form the $α$ particle. This is because the clustering induced by the pairing mode acting upon the four nucleons is inhibited if the configuration space does not allow a proper manifestation of the pairing collectivity.
