Abstract

The Fermi superallowed β+ activities Ga62, As66, and Br70 were produced in the reactions Ni58(Li6, 2n)Ga62 at ELi6=25 MeV Ni58(B10, 2n)As66 at EB10=30 MeV, and Ni58(N14, 2n)Br70 at EN14=44 MeV. Half-lives were determined by multi-scaling pulses from a plastic β ray detector. The measured half-lives are as follows: Ga62—115.95±0.30 ms, As66—95.78 ±0.39 ms, and Br70—80.2±0.8 ms. An attempt to observe the decay of Rb74, produced in the Ni58(F19, 3n)Rb74 reaction at EF19=6068 MeV, was unsuccessful.

RADIOACTIVITY Ga62, As66, Br70; measured T12.
