Phys. Rev. Lett. 72, 4066–4069 (1994)Complete 0ħω calculations of Gamow-Teller strengths for nuclei in the iron regionReceived 3 February 1994; published in the issue dated 27 June 1994 Gamow-Teller strengths for selected nuclei in the iron region (A∼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(E2,21+→01+) values are in fair agreement with experiment using effective charges of ep=1.1e and en=0.1e. © 1994 The American Physical Society URL:
