Theory of nuclear reactions

The present thesis deals with the elastic scattering of 6Li projectiles . The differential cross section and vector polarization are calculated through the calculated 6 Li optical potential and through the parametrized phase shift. In chapter 1, A survey on the theoretical methods for calculating the optical potential of composite projectiles and a survey on different parameterizations are made. In chapter 2, we have calculated 6 Li - nucleus optical potential using the watanabe folding procedure.In chapter 3, A correction to the potential calculated in chapter 2 is made using the adiabatic approximation . Also , a correction is made by a proper choice of energy at which the optical parameter sets of the constituents of 6 Li should be taken. In chapter 4, the differential cross section and vector polarization for spin-1/2 and spin-1 projectiles are calculated using Ericson parametrization and the Regge pole technique for calculating the partial wave expansion of the scattering amplitude. In chapter 5, the results of calculations are presented compared with the experimental data
