Study of the Production of Positively Charged Pions in Proton–Proton Collisions in the Range of Primary Momenta between 1345 and 1536 MeV

Differential cross sections obtained for the reaction at five incident proton momenta of 1345, 1393, 1439, 1486, and 1536 MeV/ c are presented. The respective measurements were performed with the aid of a hydrogen-filled bubble chamber. The angular and mass distributions in two-particle channels are compared with the predictions of the one-pion-exchange model and are subjected to a partial-wave analysis with the aim of determining the contributions of various partial waves to the process of pion production in the energy region being studied.
