The odd-odd nucleus ${}_{}{}^{72}{}_{}{}^{}\mathrm{Ga}$ has been studied via the ${}_{}{}^{73}{}_{}{}^{}\mathrm{Ge}$(d${,}^3$He${)}^{72}$Ga reaction at 25.2 MeV, with 9 keV resolution full width at half maximum, using a tandem accelerator and a split pole spectrometer. The spectroscopic factors are determined for 40 levels, some of which were previously unknown. All the observed levels have negative parity; limits for the spin value J are given and possible main configurations are suggested for some levels. The occupation numbers of the proton orbitals in ${}_{}{}^{73}{}_{}{}^{}\mathrm{Ge}$ have been determined: this nucleus appears in this respect as more similar to the heavier even Ge isotopes than to the lighter ones.
