WebSep 2, 2024 · The strong τ σ interaction pushes up the τ σ Gamow–Teller (GT J π = 1 +) and spin-dipole (SD J π = 2 −) strengths to form the GT and SD giant resonances (GT-GR and SD-GR) in the high-excitation region, leaving little τ σ GT and SD strengths in the ground and low-lying quasi-particle (QP) states in the intermediate nucleus of Z + 1 A ... 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 ...
