Excitation functions of (c~,xnyp) reactions on 93Nb with y<6 and x<10 have been measured in four different irradiations from 16 to 171 MeV bombarding energy by Ge(Li) spectroscopy of the residual activity of stacked foils. Similarly, previous measurements of 18~Ta(c~, xn yp) reactions from 15 to 103 MeV were extended up to 170 MeV eenergy for residual nuclei with y<4 and x<12. Including isomeric states a total number of 37 residual activities could be identified in 93Nb+e. From the rather complex y-decay spectra altogether 28 different excitation functions of sizable length could be established. For 18XTa + ~ 10 different residual activities were analyzed so that together with the former data a set of 15 excitation functions is available. The whole set of excitation functions provides a large data basis for probing the validity of combined equilibrium and preequilibrium reaction models in a wide energy range.
