Elastic scattering cross-sections of 16,18O + 120Sn reactions based on the potential of the modified Thomas - Fermi method with consideration of the core

Nucleon density distributions and nucleus-nucleus interaction potentials for the reactions 16,18O + 120Sn were obtained within the framework of the modified Thomas - Fermi method. In the calculations, all terms up to the second order in ћ in the quasi-classical distribution of kinetic energy were taken into account. Density-dependent Skyrme forces were used as nucleon-nucleon interaction. Using the found potentials, cross-sections of elastic scattering were calculated, which well describe the corresponding experimental data.
