In-beam cross section measurements of the 93Nb(p,γ)94Mo reaction have been carried out at Ep=1.4–4.9MeV, by using high efficiency high-purity Ge detectors, partly with BGO shields for Compton background suppression. From the resulting cross sections, which lie in the 0.5–300 μb range, astrophysical S factors as well as reaction rates have been obtained. By means of the statistical compound nucleus theory of Hauser and Feshbach, cross sections and reactions rates have also been calculated. A good agreement between the experimental data and the theoretical predictions has been found.
