Correlation between the quenching of total GT+ strength and the increase of E2 strength
Relations between the total beta+ 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
J=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).Comment: 11 pages and 3 figures (Figures will be sent on request
