| Popis: | The results of a study of the $\ensuremath{\beta}$ decays of three proton-rich nuclei with ${T}_{z}=\ensuremath{-}2$, namely $^{48}\mathrm{Fe},^{52}\mathrm{Ni}$, and $^{56}\mathrm{Zn}$, produced in an experiment carried out at GANIL, are reported. In all three cases we have extracted the half-lives and the total $\ensuremath{\beta}$-delayed proton emission branching ratios. We have measured the individual $\ensuremath{\beta}$-delayed protons and $\ensuremath{\beta}$-delayed $\ensuremath{\gamma}$ rays and the branching ratios of the corresponding levels. Decay schemes have been determined for the three nuclei, and new energy levels are identified in the daughter nuclei. Competition between $\ensuremath{\beta}$-delayed protons and $\ensuremath{\gamma}$ rays is observed in the de-excitation of the $T=2$ isobaric analog states in all three cases. Absolute Fermi and Gamow-Teller transition strengths have been determined. The mass excesses of the nuclei under study have been deduced. In addition, we discuss in detail the data analysis taking as a test case $^{56}\mathrm{Zn}$, where the exotic $\ensuremath{\beta}$-delayed $\ensuremath{\gamma}$-proton decay has been observed. |
