  We report here the results of a study of the $\beta$ decay of the proton-rich
Ge isotopes, $^{60}$Ge and $^{62}$Ge, produced in an experiment at the RIKEN
Nishina Center. We have improved our knowledge of the half-lives of $^{62}$Ge
(73.5(1) ms), $^{60}$Ge (25.0(3) ms) and its daughter nucleus, $^{60}$Ga
(69.4(2) ms). We measured individual $\beta$-delayed proton and $\gamma$
emissions and their related branching ratios. Decay schemes and absolute Fermi
and Gamow-Teller transition strengths have been determined. The mass excesses
of the nuclei under study have been deduced. A total $\beta$-delayed
proton-emission branching ratio of 67(3)% has been obtained for $^{60}$Ge. New
information has been obtained on the energy levels populated in $^{60}$Ga and
on the 1/2$^-$ excited state in the $\beta p$ daughter $^{59}$Zn. We extracted
a ground state to ground state feeding of 85.3(3)% for the decay of $^{62}$Ge.
Eight new $\gamma$ lines have been added to the de-excitation of levels
populated in the $^{62}$Ga daughter.
