Kuzyakin R.A., Sargsyan V.V., Adamian G.G., Antonenko N.V. Quantum Diffusion Description of LargeAmplitude Collective Nuclear Motion (rus, 3.1 Mb) Within the microscopic quantum diffusion approach, the method to calculate the probability of passing through the parabolic barrier and the quasistationary thermal decay rate from a metastable state is developed. The method is used both in the limit of linear coupling in the momentum between the collective subsystem and environment and in the more general limit of linear coupling in the momentum and the coordinate. In terms of the considered approach, the capture process of the projectile by the target nucleus is studied at bombarding energies near and below the Coulomb barrier. The analytical expression for partial capture probability which defines the formation cross section of a dinuclear system is derived. The total and partial capture cross sections, mean and meansquare angular momenta of the captured systems, astrophysical Sfactors, logarithmic derivatives, and barrier distributions are calculated for various reactions. The effects of entrance channel, isotopic composition, and nuclear deformation of interacting nuclei and neutron transfer between them on capture cross section are studied. %The effects of nuclear deformation and neutron transfer between interacting nuclei, the isotopic dependence of capture cross section, the entrance channel effects on capture process are studied. The calculated results for the reactions with spherical and deformed nuclei are in a good agreement with available experimental data.
