Abstract

It was suggested earlier that, due to the statistical properties of complicated many-body dynamics, the energies of low-lying nuclear states in large shell model spaces converge to their exact values exponentially as a function of the dimension in progressive truncation. Applying the exponential convergence algorithm as a practical method of extrapolation we calculated ground-state energies, spins, and isospins of the lowest δ(N-Z) nuclides from 42Ca to 56Ni using the fp-shell model and the FPD6 interaction. The binding energies relative to 40Ca are compared with the experimental values. The deviation can be accounted by adding monopole terms to the single-particle energies and two-body matrix elements.
