Abstract
The neutron-rich isotopes and are produced by fragmentation of a 64.5 MeV/nucleon beam in a 90 mg/ target. Following particle identification by energy loss and time of flight, the radioactive decay was observed by β singles and βγ-coincidence measurements. The results obtained for are compared to previous results, whereas the decay of the isotopes is studied here. γ-ray intensities and energies are estimated. The new experimental results are compared to quasi-random-phase-approximation predictions. © 1996 The American Physical Society.
