Proton-Proton Scattering Experiments at 170 and 260 Mev

Abstract
The differential proton-proton scattering cross section has been measured at 170 and 260 Mev for laboratory angles of 4.4° to 30°. The proton beam was obtained by reducing the energy of the 345-Mev beam of Berkeley cyclotron. A liquid-hydrogen target was used. Counting was done with a telescope of two liquid scintillation counters. A Faraday cup served as a standard for beam calibration.
