Measurement and analysis of cross sections for (p,n) reactions in 51V and 113In

Excitation functions (EFs) for the reactions 51V(p,n)51Cr up to 15 MeV and 113In(p,n)113Sn up to 20 MeV from threshold have been measured employing the stacked foil activation technique. To the best of our knowledge EF for the reaction 113In(p,n)113Sn has been reported for the first time. The theoretical analysis of the EFs has been done employing both the semi-classical as well as quantum mechanical codes which include compound nucleus and pre-equilibrium (PE) emission into consideration. In general, theoretical calculations agree well with the experimental data. Effect of various free parameters used in the calculations have also been discussed. A significant contribution of pre-equilibrium component has been observed at these energies.
