Abstract

Proton-proton elastic scattering has been measured in the region $4.9 < | t | < 12.1$ ${GeV}^{2}$ at a beam momentum of 201 GeV/c. If the form $\exp (At)$ is fitted to the data, the exponent $A$ gradually changes from 1.5 to 0.9 ${GeV}^{- 2}$ over our $t$ range. The data are consistent with the form $\exp (- 6.6 p_{⊥})$ . A comparison with intersecting storage ring results shows that in this kinematical region the slopes are about the same, but $\frac{d σ}{dt}$ at fixed $t$ is still dropping with energy.
