Abstract

The decay of 84Ga has been reinvestigated at the PARRNe online mass separator of the electron-driven installation ALTO at IPN Orsay. The nominal primary electron beam of 10 μA (50 MeV) on a 238UCx target in combination with resonant laser ionization were used for the first time at ALTO. Improved level schemes of the neutron-rich 83,84Ge (Z=32) isotopes were obtained. The experimental results are compared with the state-of-the-art shell model calculations and discussed in terms of collectivity development in the natural valence space outside the 78Ni core.
