Abstract

Abstract Angular distributions of π + and K +p elastic scattering have been measured for an incident beam momentum of 10.0 GeV/ c. For π +p elastic scattering almost the complete angular distribution was measured. The angular distribution of proton-proton elastic scattering was measured for an incident momentum of 9.0 GeV/ c in the interval of the four-momentum transfer squared from 0.7 (GeV/ c) 2 to 5.0 (GeV/ v) 2. For π +p elastic scattering the structures at − t = 2.8 (GeV/ c) 2 and − t = 4.8 (GeV/ c) 2 are less pronounced than at lower momenta. The cross section for scattering at 90° in the c.m. system is of the order of 1 nb/GeV/ c) 2. For K +p elastic scattering is a break in the angular distribution around − t = 3 (GeV/ c) 2. The differential cross sections for proton-proton elastic scattering decrease smoothly with increasing momentum transfers.
