The asymptotic feature of diffraction scattering of hadrons is tentatively assumed to mean asymptotically pure-imaginary partial waves. An essential requirement is then inferred to be the existence of an infinity of reaction channels and asymptotically infinite inelasticity (assuming asymptotic vanishing of partial-wave amplitudes). This view is supported by construction of a physically sensible inelastic model which has all the above features. Finally, these assumptions are shown to imply asymptotic vanishing of form factors; this resolves a puzzling feature of conventional dispersion-theory solutions for form factors.
