Study Of Reaction Mechanism In P 133 Cs Systems At Various Energies Of Protons

In this thesis proton induced reaction on Cesium 133Cs for various energy of protons havernbeen studied. Excitation function (EFs) for ve reactions of the type 133Cs(p; n)133Barn, 133Cs(p; n + p)132Cs , 133Cs(p; 3n)131Ba, 133Cs(p; 5n)129Ba and 133Cs(p; 6n)128Ba werernstudied. Theoretical calculations have been carried out by using code COMPLET in-rncludes both compound nucleus (CN) as well as pre - compound (PC). The theoreticalrnresults are compared with the experimental excitation functions obtained from EXFORrndata source,IAEA. The study shows that high energy parts of excitation functions arerndominated by pre - equilibrium reaction mechanism where as the low energy parts arerndominated by compound nucleus reaction mechanism. The percentage of pre - equilib-rnrium factor contribution is found to increase with normalized projectile energy and whenrnthe incident proton energy increases the pre - equilibrium reaction is more sign cant
