Abstract
We calculate in our formulation of the elastic and inelastic breakup process in nucleus-nucleus collisions the corresponding flux removed from the elastic channel. It is the dominant reaction mode for surface partial waves. Strongly reminiscent of the Serber model, the absorption can be characterized by "geometrical" quantities (radius of the projectile and target nucleus) and a "strength parameter" which becomes constant for energies much larger than the binding energy of the projectile.
