Abstract
In this work C-12 induced reaction on Gold( 197Au) in the energy range of 59Mev to 91Mev
have been studied. Excitation function for four reactions of the type 197Au(12C; 3n)206At,
197Au(12C; 4n)205At, 197Au(12C; 5n)204At and 197Au(12C; 6n)203At were studied in these
reactions. For theoretical excitation function the computer code COMPLET have been
used. The theoretical results are compared with the experimental excitation functions
obtained from EXFOR data source,IAEA to verify signatures of pre-equilibrium decay.The
study shows that at intermediate energy, carbon induced reactions on high weight nuclei
occurs through pre-equilibrium and equilibrium(compound) nucleus stages and not only
by compound nucleus formation
