Abstract

The β decay of Zn57 and Zn58 was investigated in an experiment at the National Superconducting Cyclotron Laboratory of Michigan State University. For the first time β-delayed proton emission from Zn58 was observed with a branching ratio of 0.7(1)%. The proton-energy spectrum allowed for probing the Gamow-Teller strength distribution above the proton-separation energy in the daughter nucleus. Moreover, the absolute branching ration for delayed-proton emission from Zn57 was found to be compatible with 100%.
