Abstract Excitation functions of (α,xn yp) reactions on93Nb withy≦6 andx≦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 of181Ta(α,x n y p) reactions from 15 to 103 MeV were extended up to 170 MeVα-energy for residual nuclei withy≦4 andx≦12. Including isomeric states a total number of 37 residual activities could be identified in93Nb+α. From the rather complexγ-decay spectra altogether 28 different excitation functions of sizable length could be established. For181Ta+α 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.
