    • Abstract


      Stacked foil activation technique and Ge(Li) gamma ray spectroscopy have been used for the measurement of excitation functions of197Au(α,xn) (x=1−3),197Au(α,2pn) and197Au(α,αn) reactions up to 50 MeV. The experimental cross-sections were compared with the predictions of pre-equilibrium hybrid model, as well as with the more recent index model. A general agreement was found in all reactions using initial exciton numbern0=4(4p0h) except for197Au(α,n) reaction, where index model gives fairly good agreement withn0=5(5p0h).
