Deep--elastic scattering and asymptotics

Deep--elastic scattering and its role in discrimination of the possible absorptive and reflective asymptotic scattering mechanisms are discussed with emphasis on the difference in the experimental signatures related to production processes.Comment: 8 pages, no figures, added discussions and reference
