摘要
The shell-model effective interaction GXPF1 is tested for the description of unstable pf-shell nuclei. The GXPF1 successfully describes the N = 32 shell gap in Ca, Ti and Cr isotopes, while the deviation of predicted E-x(2(1)(+)) in Ti-56 from the recent experimental data requires the modification of the Hamiltonian especially in the T = I. matrix elements related to the p(1/2) and f(5/2) orbits. The modified interaction gives improved description simultaneously for all these isotope chains.
