β-delayed γ-proton decay in 56Zn: Analysis of the charged-particle spectrum

Abstract

A study of the β decay of the proton-rich Tz = -2 nucleus 56Zn has been reported in a recent publication. A rare and exotic decay mode, β-delayed γ-proton decay, has been observed there for the first time in the fp shell. Here, we expand on some of the details of the data analysis, focussing on the charged particle spectrum.
