摘要
We have calculated level densities for Cr48-50 and Mn-50,Mn-51 using the Shell Model Monte Carlo method. As residual interaction we use a pairing + quadrupole force supplemented by an additional isospin repulsion which is treated in perturbation theory. The SMMC results compare favorably with empirical backshifted Fermi gas level densities. (C) 1998 Elsevier Science B.V. All rights reserved.
