摘要：

The paper is focused on reaction dynamics of superheavy nucleus formation and decay at beam energies near the Coulomb barrier. The aim is to review the things we have learned from recent experiments on fusion-fission reactions leading to the formation of compound nuclei with Z >= 102 and from their extensive theoretical analysis. The choice of collective degrees of freedom playing a principal role and finding the adiabatic multi-dimensional driving potential regulating the whole process are discussed. Dynamics of heavy-ion low energy collisions is studied within the realistic model based on multi-dimensional Langevin equations. Theoretical predictions are made for synthesis of SH nuclei in symmetric and asymmetric fusion reactions as well as in damped collisions of transactinides.
