The features of the processes of formation and decay of transuranium nuclei formed in the reactions of complete fusion of heavy ions are analyzed. When analyzing the experimental data for the $^{16}$O+$^{232}$Th, we used quantum-mechanical calculations of the initial distributions for the components of the total angular momentum of the compound nuclei $^{248,247}$Cf and the dynamic ssion model to describe their decay. It is shown that the eects of <<memory>>on the characteristics of the entrance channel of a reaction associated with the presence of spins and deformations in colliding nuclei play an important role in the formation of angular distributions of ssion fragments.
