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 formationenPre-Equilibrium Reactions in 12C +197 AU SystemsThesis
