Study of the quenching of the GT-decay operator in a microscopic shell-model approach

Abstract The need of a reliable calculation of the nuclear matrix elements for the 0 νββ decay has ignited a new interest about the quenching of the axial coupling constant g A , a procedure introduced to reproduce experimental results connected with GT decays. The goal of this work is to present a...

Summary:Abstract The need of a reliable calculation of the nuclear matrix elements for the 0 νββ decay has ignited a new interest about the quenching of the axial coupling constant g A , a procedure introduced to reproduce experimental results connected with GT decays. The goal of this work is to present a preliminary study to tackle this problem within the framework of the realistic shell model.
