第３５回つくば不安定核セミナー

概要

Gamow-Teller(GT) transitions are caused by the simple στ operator [1] and are the most common weak process in the Universe. They play important roles invarious processes of nucleosynthesis.

Under the assumption of isospin symmetry, mirror nuclei with reversed Z and N numbers have the same structure and symmetry is expected for the GT transitions starting from them [1]. We have been studying GT transitions by means of (³He,t) charge-exchange reactions, i.e., strong interaction and complementary β decays, i.e., weak interaction. The results from these studies are compared and combined for the better understanding of nuclear structure [2] as well as nuclear interactions [3].
