Proton-Proton Differential Cross Sections from 600 to 1800MeVc

Proton-proton elastic differential cross sections have been measured for incident laboratory momenta of 600-1800 $\frac{\mathrm{MeV}}{c}$ and c.m. angles of 5°-90°. The data span, in a single experiment, the intermediate energy region from isotropic differential cross sections at lower energies to the development of a clear diffraction peak at higher energies. Parameters for phenomenological formulations derived from the experimental results are presented.
