Study of correlations between secondary protons produced in proton-neon interactions at 300 GeV/c

Data on two- and three-proton correlations in proton-neon interactions at 300 GeV/c are presented. It is found that the two-proton correlation increases as the average proton momentum increases. From this two-proton correlation we estimate the size of the proton-emission region to be less than 1 fm for high-energy protons (> 700 MeV/c). There is some indication of a spherical asymmetry in the shape of proton-emission source. The data also show evidence for the presence of three-proton correlations.
