Abstract
The neutron-rich isotopes Ti-54-57 and Cr-58-60 are produced by fragmentation of a 64.5 MeV/nucleon Cu-65(26+) beam in a 90 mg/cm(2) Be-9 target. Following particle identification by energy loss and time of flight, the radioactive decay was observed by beta singles and beta gamma-coincidence measurements. The results obtained for Cr-58-60 are compared to previous results, whereas the decay of the Ti-54-57 isotopes is studied here. gamma-ray intensities and energies are estimated. The new experimental results an compared to quasi-random-phase-approximation predictions.
