Abstract
Proton-proton scattering between 200 and 300 kev has been studied as a function of energy and of angle. The results are in good agreement with Breit's calculations based on a square well proton-proton interaction potential of radius and 10.500 Mev depth. The scattering chamber was isolated from the accelerating tube by a differential pumping system. Scattered protons were detected by Geiger-Klemperer proportional counters filled with purified hydrogen. Two separate counters connected to similar amplifier-recorder circuits detected simultaneously protons scattered at different angles from the beam, and the ratio of scattering at these angles was calculated directly. Tests of the performance of the counters are given. Two different scattering chambers yielded similar results.
