Abstract

A unified quantal description of the wave mechanical and semiclassical aspects of heavy ion collisions is given by means of closed expressions derived from partial-wave expansion of the transition amplitudes. The results depend entirely on the asymptotic properties of the scattering wave functions (the partial-wave S matrix). It is shown, in particular, how the “refractive” features of semiclassical potential scattering are changed, in the presence of absorption, into characteristic quantal interference patterns of “diffractive” type. Only the simplest idealized limits are considered as examples of how insight is gained into the physical mechanisms that operate under various scattering conditions. Elastic scattering, inelastic scattering, and direct transfer reactions are described and the close physical connexion between these processes is made explicit.
