Abstract：
The calculations of nucleus-nucleus potential are carried out in the framework of double folding model with M3Y-Reid and M3Y-Paris effective nucleon-nucleon (NN) interactions. The exchange part of the interaction, which is taken to be of finite range and the density dependence of NN interaction, is accounted for in the folding procedure. The results are used as the real part of the optical potential for heavy ion scattering. Besides, some general aspects of the folding model are reviewed and its theoretical processes are discussed. The calculated potentials with all kinds of NN interactions are compared. It is shown that the real parts of the optical potential for a large number of systems are obtained satisfactorily with our double folding model. Therefore, this work provides a promising way for a systematic and comprehensive double folding calculation of heavy ion interaction potential.
