Scheme of the $_{}^{75}$Ge ground state $\beta$-decay to $_{}^{75}$As and subsequent $\gamma$-decays, adapted from [16]. The $\beta$-decay (E$_{\beta }^{}$ = 912.6 keV) to the second excited $_{}^{75}$As state in coincidence with the 264.60 keV $\gamma$-ray is used to tag both the neutron and proton disappearance in $_{}^{76}$Ge. Level and $\gamma$-ray of interest are highlighted in red. The transition $_{}^{75}$Ga${\to }^{75}$Ge following $_{}^{76}$Ge proton decays is shown in blue
