Nuclear optical model potential : proceedings of the meeting held in Pavia, April 8 and 9, 1976

The various formal derivations of the theoretical optical potential for scattering problems are outlined and their connections are discussed. Such a survey concerns the time dependent derivations as well as the stationary formulations in terms of the spectral properties of the many body system, of the nucleon-nucleon scattering amplitude and of the mass operator. The different pieces of information that every formulation gives are pointed out and the situations where each representation of theoretical optical potential is more suitable to obtain particular results are discussed. A brief comment on the mathematical and formal attitudes to handle this problem is also made.
