Resumen:
|
The existence of two close-lying nuclear states in ?³Ga has recently been experimentally determined: a 1/2? spin-parity for the ground state was measured in a laser spectroscopy experiment, while a J_? = 3/2? level was observed in transfer reactions. This scenario is supported by Coulomb excitation studies, which set a limit for the energy splitting of 0.8 keV. In this work, we report on the study of the excited structure of ?³Ga populated in the ? decay of ?³Zn produced at ISOLDE, CERN. Using ?-gated, ?-ray singles, and ? –? coincidences, we have searched for energy differences to try to delimit the ground-state energy splitting, providing a more stringent energy difference limit. Three new half-lives of excited states in ?³Ga have been measured using the fast-timing ;method with LaBr?(Ce) detectors. From our study, we help clarify the excited structure of ?³G and we extend the existing ?³Zn decay to ?³Ga with 8 new energy levels and 35 ? transitions. We observe a 195-keV transition consistent with a ? ray de-exciting a short-lived state in the ?-decay parent ?³Zn.
