The formation of 73Ga through natGe(n,x)73Ga reaction induced by d-T neutrons was investigated using cross-sections measured by four characteristic gamma-rays employing the weighted average method. The neutron energy and uncertainty were determined by the Q equation of reaction 3H(d,n)4He combined with the solid angle of the sample. The gamma spectrum of the activated sample was obtained by an off-line technique using a high-resolution, high-purity germanium detector (HPGe). The contribution of nuclear reactions 76Ge(n,α)73Zn, 73Ge(n,p)73Ga, and 74Ge(n,d∗)73Ga to residual nuclei 73Ga was analyzed and the cross-sections of reaction 73Ge(n,p)73Ga were determined with a small uncertainty. The TALYS-1.96 package was utilized for performing the theoretical calculation of the cross section of 76Ge(n,α)73Zn, 73Ge(n,p)73Ga, and 74Ge(n,d∗)73Ga reactions. The results of the theoretical calculation of nuclear reaction 73Ge(n,p)73Ga were compared with the experimental measurements and the evaluation results provided by the database.
