The decay of75Ga to levels in75Ge

  • 15 Accesses

  • 8 Citations


The decay of75Ga has been investigated with Ge(Li) spectrometers. Energy and intensity determinations for 37 gamma rays have been performed. A level scheme for75Ge was deduced, where 31 gamma transitions could be placed. Beta branch intensities were estimated from the measured gamma intensities. Spin and parity assignments for most of the levels were made in agreement with reaction and neutron capture studies. Half life of75Ga was measured to be (130±6) sec and that of the 139.3 keV isomeric state in75Ge to be (47.7±0.5) sec.
