Abrupt changes in alpha decay systematics as a manifestation of collective nuclear modes

Nuclear Theory 2014-11-20 v2

Abstract

An abrupt change in α\alpha 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\alpha 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.
