Computation of Nuclear Reactions with Light-Heavy Ions

Abstract

The computer code OLYMPS for calculation of the inclusive cross sections for nuclear reactions induced by light heavy ions on medium-mass nuclei at beam energies of 10–20 MeV per nucleon is developed. Our calculations are based on the description of the massive transfer reactions in the spectator model. In view of the fact that most of the considered reactions have more than two particles in the final state and require an allowance for the continuum spectrum, the standard distorted wave Born approximation (DWBA) code fails to work. In our method the transition amplitude is witten in a prior-form of exact finite range DWBA and an exact numerical integration over the transfer momentum is carried out. This requires knowledge of the optical potentials between interacting light and heavy ions in a wide energy range. In addition, OLYMPS provides for the alternative ways of calculation of the wave functions of the relative motion of the heavy ions.
