[en] For the better understanding of the astrophysical γ-process the experimental determination of low energy proton- and α-capture cross sections on heavy isotopes is required. The existing data for the ⁹²Mo(p,γ)⁹³Tc reaction are contradictory and strong fluctuation of the cross section is observed which cannot be explained by the statistical model. In this paper a new determination of the ⁹²Mo(p,γ)⁹³Tc and ⁹⁸Mo(p,γ)^99mTc cross sections based on thick target yield measurements are presented and the results are compared with existing data and model calculations. Reaction rates of ⁹²Mo(p,γ)⁹³Tc at temperatures relevant for the γ-process are derived directly from the measured thick target yields. The obtained rates are a factor of 2 lower than the ones used in astrophysical network calculations. It is argued that in the case of fluctuating cross sections the thick target yield measurement can be more suited for a reliable reaction rate determination
