摘要：

Gamow-Teller strengths for selected nuclei in the iron region (A approximately 56) have been investigated via shell-model Monte Carlo calculations with realistic interactions in the complete fp basis. Results for all cases show significant quenching relative to single-particle estimates, in quantitative agreement with (n,p) data. The T = 0 residual interaction and the f7/2-f5/2 spin-orbit splitting are shown to play major roles in the quenching mechanism. Calculated B(E2,2(1+) --> 0(1+)) values are in fair agreement with experiment using effective charges of e(p) = 1.1e and e(n) = 0.1e.
