Abstract.

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 Ex(2+1) in 56Ti from the recent experimental data requires the modification of the Hamiltonian especially in the T = 1 matrix elements related to the p1/2 and f5/2 orbits. The modified interaction gives improved description simultaneously for all these isotope chains.
