Abstract

Relations between the total β+ Gamow-Teller (GT+) strength and the E2 strength are further examined. It is found that in shell-model calculations for N = Z nuclei, in which changes in deformation are induced by varying the single-particle energies, the total GT+ or GT- strength decreases monotonically with increasing values of the B(E2) from the ground state to the first excited Jπ = 2+ state. Similar trends are also seen for the double GT transition amplitude (with some exceptions) and for the spin part of the total M1 strength as a function of B(E2).
