nucleus-nucleus interaction potential, modified Thomas–Fermi method, nucleon density distribution, repulsive core, analytical representationAbstract
Nucleon density distributions and nucleus-nucleus interaction potentials of the 16O nucleus with the 56,58,60,62,64Ni isotopes have been calculated in the framework of the modified Thomas–Fermi method, i.e., considering all terms up to the second order in ħ in the quasi-classical series expansion of the kinetic energy. Skyrme forces dependent on the nucleon density are used as the nucleus-nucleus interaction. A successful parametrization of the obtained potential has been found, which allowed the latter to be presented in an analytical form.
