摘要：

We study the gross properties of even-even and N = Z nuclei with A=48-64 using shell-model Monte Carlo methods. Our calculations account for all 0HBARw configurations in the fp shell and employ the modified Kuo-Brown interaction KB3. We find good agreement with data for masses and total B(E2) strengths, the latter employing effective charges e(p) = 1.35e and e(n) = 0.35e. The calculated total Gamow-Teller strengths agree consistently with the B(GT(+)) values deduced from (n,p) data if the shell-model results are renormalized by 0.64, as has already been established for sd-shell nuclei. The present calculations therefore suggest that this renormalization (i.e., g(A) = 1 in the nuclear medium) is universal.
