We demonstrate the feasibility of realistic shell-model Monte Carlo (SMMC)
calculations spanning multiple major shells, using a realistic interaction
whose bad saturation and shell properties have been corrected by a newly de
veloped general prescription. Particular attention is paid to the approxima
te restoration of translational invariance. The model space consists of the
full sd-pf shells. We include in the study some well-known T = 0 nuclei an
d several unstable neutron-rich ones around N= 20,28. The results indicate:
that SMMC calculations can reproduce binding energies, B(E2) transitions,
and other observables with an interaction that is practically parameter fre
e. Some interesting insight is gained into the nature of deep correlations.
The validity of previous studies is confirmed. [S0556-2813(99)00405-7].
