Abstract
A new procedure is developed for calculating the charge, mass, and kinetic energy distributions of quasifission products. The quasifission is treated within a transport model which describes a master equation for the evolution of the dinuclear system in charge and mass asymmetries and its decay along the internuclear distance. The calculated yields of quasifission products and their distributions in kinetic energy are in agreement with recent experimental data of hot fusion reactions leading to superheavy nuclei. The importance of shell and deformation effects in quasifission is noted. The preneutron and postneutron emissions as well as the fission of a heavy nucleus in the dinuclear system are considered.
