Description
In order to calculate potential energy of two reacting heavy ions different methods are applied. The folding procedure with effective nucleon-nucleon interaction and effective internucleus potentials are widely used [1].
In this report the calculations of diabatic potential energy are carried out for spherical even-even nuclei with Z, N ≥ 8. Potential is obtained with internucleon Migdal forces [2] folded with density distribution that is chosen as a two-parameter Fermi-distribution. Special attention is paid to the choice of nucleonic density parameters: half-density radius and diffuseness. Finally, gained results are compared with the proximity potential [3] and Bass potential [4].
