Structure of {sup 52,54}Ti and shell closures in neutron-rich nuclei above {sup 48}Ca.
The level structure of {sup 54}{sub 22}Ti{sub 32} has been explored for the first time by combining {beta}-decay measurements from fragmentation products with prompt {gamma}-ray spectroscopy following deep inelastic reactions. The latter technique was also instrumental in tracing {sup 52}Ti{sub 30} to higher spin. The data provide new tests of effective interactions for full pf-shell calculations in neutron-rich nuclei above {sup 48}Ca. The data indicate the presence of a significant subshell gap at N=32 and comparisons between theory and experiment suggest an additional shell closure at N=34 in Ca and Ti isotopes.
