In the dinuclear system formed in heavy-ion collisions the nucleon exchange between two touching nuclei is described by solving the Master Equation numerically since the driving force, which contains structure effects, is not linear with mass asymmetry in the diffusion process. The relative motion is treated to couple with the nucleon exchange. All channels of every mass combination between the projectile-like and the target-like may open, and a small fraction of mass distribution probability is found to contribute to the compound nuclear formation of a super heavy nucleus in the very strongly damped reaction process.
