Abstract

A new level scheme of Ga-80 has been determined. This nucleus was populated following the beta(-) decay of Zn-80 at ISOLDE, CERN. The proposed level scheme is significantly different compared to the previously reported one and contains 26 levels up to 3.4 MeV in excitation energy. The present study establishes that the previously identified 1.9-s beta(-)-decaying 6(-) isomer is the ground state of 80Ga and the 1.3-s beta(-)-decaying 3(-) isomer lies at an excitation energy of 22.4 keV. A new isomeric level was identified at 707.8 keV and its half-life was measured to be 18.3(5) ns, allowing the 685.4-keV transition de-exciting this state to be assigned an M2 multipolarity. The newly measured spectroscopic observables are compared with shell-model calculations using the jj44bpn and JUN45 interactions.
