Excitation functions for the production of194Au,195(m+g)Au,196(m+g)Au,198mAu,195gAu and199Au were determined experimentally. In addition, the yields of thick targets of these products were calculated and a comparison between the cross sections obtained using the hybrid model of pre-equilibrium reactions in combination with the statistical model of compound nucleus is presented. The method of activation of metallic foils was employed. The irradiations were performed in the internal beam of the isochronous cyclotron at Karlsruhe (FRG) with -particles at 90 MeV. Gamma-spectrometry by means of an intrinsic Ge detector was used to determine the nuclides produced.
