Description

Excitation functions for the reactions 197Au(α,xn)201-xTl(x=1-4) have been measured in the energy range approx. 30-60 MeV using stacked foil technique. Ge(Li) gamma ray spectroscopy has been used for the analysis of irradiated samples. Excitation functions have also been calculated theoretically using two different computer codes (ACT and ALICE) with and without the inclusion of pre-equilibrium emission. As expected inclusion of pre-equilibrium emission to the compound nucleon calculations agree well with the experimentally measured excitation functions. An interesting trend in pre-equilibrium fraction with energy has been observed. (author). 33 refs, 6 figs
