Time-dependent microscopic description of total reaction cross sections for collisions of 6He and 9Li nuclei with 28Si nuclei at low and intermediate energies

Abstract

A microscopic description is given for the collisions of the 9Li and 6He nuclei with the 28Si nucleus. It is based on numerical solution of the time-dependent Schrodinger equation for the external neutrons of the projectile nuclei. The corrections to the nucleus–nucleus potential associated with the redistribution of external neutrons were determined for energies of 5 to 60 MeV/nucleon using the time-dependent folding potential. The probability of leaving the elastic channel was calculated using the reflectionless boundary condition for partial waves. The calculated cross sections are in agreement with the experimental data on the total cross sections for the above reactions.
