Abstract: (Elsevier)
Proton-proton interactions above 100 GeV have been studied in an experiment using cosmic-ray protons interacting in a liquid hydrogen target. From several hundred hydrogen interactions, it has been learned that: (a) the total inelastic pp cross section is not changing significantly with energy above 30 GeV; (b) the multiplicity distributions of charged prongs agree with a Poisson distribution in charged-particle pairs; (c) the average charged prong multiplicity increases as 1 n s ; (d) the angular distribution of charged particles agrees with a c.m. momentum distribution of charged particles that varies as exp exp [−8 p T 2 −8 x 2 ] d 3 p / E (where x = p L / p o ) and a nucleon distribution that varies as 10 x exp [−3 p T 2 ] d 3 p / E for 0.05 < × < 0.85. Further properties of the angular distributions, characteristics of the ionization calorimeter, the cross section in iron, and other features of the data are reported.- cosmic radiation
