ABSTRACT

The in-medium effects in nucleon-nucleon cross-section were treated using different approaches. We study the variation of sR with different values of rms. Also we study the variation of sR with different values of incident energy per projectile nucleon for light interacting pair 12C-12C and heavy target nucleus pair12C-208Pb.The coulombs repulsion was taken into consideration by assuming a simple model. We found that the in-medium effects on sR are small when the target nucleus becomes heavy.
