XCIX. Proton-proton elastic scattering at 950 m e v

Abstract

Ilford G5 emulsions exposed to a 950 mev proton beam from the Birmingham synchrotron, have been searched for proton-proton elastic collisions. Forty-six such events have been found in 950 metres of proton track, equivalent to a cross section for elastic scattering of 15·5±2·5 mb. The angular distribution of the scattered protons in the centre-of-mass system shows a strong forward peak in agreement with results obtained at Brookhaven by cloud chamber and counter workers.
