Title: Geometrical aspects of high energy elastic scattering. [50 to 200 GeV/c, scaling, crossover, peripherality, scattering amplitudes]

;

New Fermilab ..pi../sup +-/p, K/sup +-/p, p/sup +-/p elastic scattering data from 50 to 200 GeV/c are discussed. Each channel seems to approach geometrical scaling, with crossing-related pairs differing only in radial scale. This implies a simple crossover formula, and peripherality for the imaginary parts of crossing-odd amplitudes. The data are consistent with a single universal function describing all channels, with adjustable opacity and radial scales; however, this function must be close to the eikonal or unabsorbed overlap function, and cannot be the elastic amplitude nor the complete overlap function.
