Abstract: In the dinuclear system conception, the master equation is solved numerically to calculate the fusion probabilities of superheavy nuclei. The relative motion concerning the energy, the angular momentum and the fragment deformation relaxations is explicitly treated to couple with the diffusion process. The nucleon transition probabilities, which are derived microscopically, are related with the energy dissipation of the relative motion, thus they are timedependent. The formation cross sections of the superheavy nuclei from Pbbased cold fusion and excitation functions from 48Ca induced hot fusion are reasonably consistent with known experimental data.
