WebThe resulting total Gamow-Teller strength observed in the (p,n) reaction is about two-thirds of the minimum value required by the sum rule for a T=1 nucleus. This result is in reasonable agreement with the total Gamow-Teller strength predicted from a shell-model calculation which uses empirically renormalized single-particle Gamow-Teller matrix ...
