Abstract: (APS)
A new germanium isotope, Ge65, has been produced by the (α, 3n) reaction on Zn64. The mass assignment was established through cross bombardments, "milking" experiments, and excitation function measurements. The half-life of Ge65 is 1.5±0.2 minutes. It decays by positron emission to 15-minute Ga65. The ground-state transition occurs in over 90% of the disintegrations and has a positron end-point energy of 3.7±0.4 Mev and a log(ft) value of 4.8. Gamma rays of 0.67 Mev and 1.72 Mev have been observed with intensities of 0.03β+ and 0.02β+, respectively.References(8)
