Wave packet scattering model with quantum friction for heavy-ion collisions

Abstract

The model reaction 11B + 159Tb at 51 MeV is treated in a quantum mechanical wave packet scattering model and the results are compared with classical trajectory calculations. In the course of evolution of the wave packet, it splits up into well-separated elastic (or quasielastic), deep-inelastic (or direct), and fusion components. Probabilities for these events are deconvoluted with the initial angular momentum distribution and critical and maximum angular momenta as well as fusion, deep-inelastic and reaction cross sections are calculated. The quantum effects tend to soften the sharp l cr, l max values of the classical trajectory model, thus spreading the cross sections over a wider range of l-values, thereby enhancing the deep-inelastic cross section and reducing the fusion cross section.
