Azimuthal angle dependence of Coulomb and nuclear interactions between two deformed nuclei

Abstract

The azimuthal angle ({phi}) variation of the Coulomb and nuclear heavy ion (HI) potentials is studied in the framework of the double folding model, which is derived from realistic nuclear density distributions and a nucleon-nucleon (NN) interaction. The present calculation shows that the variation of HI potentials with the azimuthal angle depends strongly on the range of the NN forces. For the long-range Coulomb force, the maximum variation with {phi} is about 0.9%, and for HI potential derived from zero-range NN interaction the {phi}-variation can reach up to 90.0%. Our calculations are compared with the recent {phi}-dependence of the HI potential derived from proximity method. The present realistic {phi}-dependence calculations of the HI potential is completely different from the results of the proximity calculations.
