Quasi-elastic and deep-inelastic dissipative processes

Quasi-elastic and deep inelastic rates are calculated assuming that the colliding nuclei move on classical trajectories and that the excitations and the particle or energy exchanges are due to the shell-model wells interacting with the nucleons. (One-body collisions). This allows a microscopic, parameter free, calculation of the optical potential, as well as the energy and the angular momentum losses, and is a good approximation as long as the collision is peripheral. The correction due to two-body collisions between individual nucleons is also evaluated. The focus will be on the evolution of the various reaction rates as a function of energy. The system chosen for the discussion is ¹⁶O + ¹⁶O from 3 MeV/A to 60 MeV/A.
