Abstract

A half-life of 0.55 0.02 s was measured for the neutron-rich fission-product nucleus 3080Zn50. A Qβ value for the decay of 80Zn of 7.15± 0.15 MeV and a level scheme for 80Ga have also been deduced. The properties of this N=50 waiting-point nucleus are significant for the evaluation of different models of r-process environments and exposure times.
