We have measured the elastic cross section for pp, p-barp, ..pi../sup +/p, ..pi../sup -/p, K/sup +/p, and K/sup -/p scattering at incident momenta of 70, 100, 125, 150, 175, and 200 GeV/c. The range of the four-momentum transfer squared t varied with the beam momentum from 0.0016< or =-t< or =0.36 (GeV/c)/sup 2/ at 200 GeV/c to 0.0018< or =-t< or =0.0625 (GeV/c)/sup 2/ at 70 GeV/c. The conventional parametrization of the t dependence of the nuclear amplitude by a simple exponential in t was found to be inadequate. An excellent fit to the data was obtained by a parametrization motivated by the additive quark model. Using this parametrization we determined the ratio of the real to the imaginary part of the nuclear amplitude by the Coulomb-interference method.
