    Study of Reaction Mechanism in P +133 CS Systems at various Energies of Protons
    (Addis Ababa University, 2013-06) Asresahagn, Konjit
    In this thesis proton induced reaction on Cesium 133Cs for various energy of protons have been studied. Excitation function (EFs) for ve reactions of the type 133Cs(p; n)133Ba , 133Cs(p; n + p)132Cs , 133Cs(p; 3n)131Ba, 133Cs(p; 5n)129Ba and 133Cs(p; 6n)128Ba were studied. Theoretical calculations have been carried out by using code COMPLET in- cludes both compound nucleus (CN) as well as pre - compound (PC). The theoretical results are compared with the experimental excitation functions obtained from EXFOR data source,IAEA. The study shows that high energy parts of excitation functions are dominated by pre - equilibrium reaction mechanism where as the low energy parts are dominated by compound nucleus reaction mechanism. The percentage of pre - equilib- rium factor contribution is found to increase with normalized projectile energy and when the incident proton energy increases the pre - equilibrium reaction is more sign cant
