摘要：

Through a sequence of large scale 0 (h) over bar omega shell model calculations, Gamow-Teller strengths (S-+ and S--) in Fe-54 and Fe-56 are obtained. They reproduce the experimental values by quenching the sigma tau operator through the standard factor of 0.77. Comparisons are made with recent shell model Monte Carlo calculations. Results are shown to depend critically on the interaction. It is argued that the experimental data contain enough strength in the region above the resonance to make them consistent with the 3(N-Z) sum rule.
