Abstract
The problem of taking into account radial and tangential friction in the entrance channel of \({}^{36}\textrm{S}+{}^{238}\) U and \({}^{64}\textrm{Ni}+{}^{238}\) U nuclear reactions occurring at a nonzero impact parameter is considered. The reactions in question are simulated in the approximation of frozen deformation degrees of freedom of colliding nuclei. The shape of the target nucleus is elongated, and its symmetry axis is oriented arbitrarily in the plane drawn through the initial projectile momentum and the center of mass of the target nucleus. The shape of the projectile nucleus remains spherical throughout the process of collision of primary nuclei. The dynamical evolution of two degrees of freedom of the system is considered; these are a parameter that describes the distance between the centers of mass of colliding nuclei and a parameter that describes the orientation of the target nucleus. It is shown that the inclusion of tangential friction between colliding nuclei makes it possible to avoid overestimating the probability for projectile capture by the target nucleus at high angular momenta. The results of the simulation are compared with experimental data and with the results of calculations based on the earlier version of the model.
