Abstract
γ rays from neutron-rich Ti nuclei in the vicinity of have been studied at Gammasphere using deep-inelastic reactions induced by beams on thick and targets. The yrast cascade was identified for the first time, and the location in energy of states with spin up to I = 21/2 was determined. The excitations of provide new tests of effective interactions for full-pf-shell calculations. Comparisons between theory and experiment for the highest spin states in favor the recently proposed GXPF1A interaction, which accounts for the appearance of a neutron subshell closure at in Ti isotopes as well as for the lack of a similar subshell closure at , as predicted by earlier calculations with another interaction.
