Microscopic Study of the Nucleus-Nucleus Interaction on the Basis of the Realistic Effective Interaction. I Formulation

We investigate the inter·nucleus complex potential by the many body theory containing the Pauli principle entirely and by the microscopic scattering state complex G·matrix. Our main purpose is to investigate the nature of the imaginary part of the nucleus· nucleus potential as well as the real part of it. In order to obtain the complex inter-nucleus potential by the complex G·matrix, we refor· mulate and extend the many body theory (CMWP) originally formulated for the calculation of the' real inter·nucleus potential by Saraceno et a!. And also we show how to treat the density dependence of the G·matrix. To ensure the reliability of CMWP we make a comparison between the numerical results by the CMWP method and the reliable RGM + WKB method. As a result we have found reliability and great facility.of CMWP.
