EFFECTIVE NUCLEUS-NUCLEUS POTENTIAL FOR CALCULATION OF POTENTIAL-ENERGY OF A DINUCLEAR SYSTEM

An effective method to calculate the potential energy of a dinuclear s ystem is suggested. The nuclear part of the nucleus-nucleus potential is taken in the double folding form. The analytical expressions obtain ed allow one to simplify the calculations of interaction between two n uclei except the nuclei near the drip lines. The relationship between the double folding potential and the proximity potential is found. The influence of a deformation and a relative orientation of nuclei on th e interaction potential is investigated. The method is applied to the calculations of the energies of the dinuclear and trinuclear systems.
