Item Study of Proton Induced Reaction Cross Section for Various Energies on Yttrium and Scandium(Addis Ababa University, 2007-07) Ayele, Getaneh; Chaubey, Ashok K (Professor)Reaction cross section for (p, n) reaction in 45-Y and 89-Sc were studied for various incident energy of proton and experimental results have been compared with the theoretical calculated ones. Targets were isotopes of Yttrium and Scandium in the intermediate mass ranges .Excitation functions (EFs) for both reactions due to the various energies from the threshold have been studied. The theoretical analysis of the EFs has been done employing both semi-classical and quantum mechanical codes which include compound nucleus and pre equilibrium emission into consideration. Effects of various free parameters used in the calculations have also been discussed by the means of the graphs
