First identification of Zn58 β -delayed proton emission

Abstract: The β decay of 57 Zn and 58 Zn was investigated in an experiment at the National Superconducting Cyclotron Laboratory of Michigan State University. For the first time β-delayed proton emission from 58 Zn 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 57 Zn was found to be compatible with 100%.

“…[395][396][397]). Recent decay studies have focused on β-delayed particle emission probabilities (e.g., [379,[398][399][400][401][402]). Modifications of β-decay rates in the astrophysical environment, for example due to continuum electron capture, have been calculated and are significant in some cases [403].…”
