Differential cross sections from kinematically complete measurements of {ital pp}{r_arrow}{ital pn}{pi}{sup +} production are presented for proton beam energies of 294.2, 299.5, and 319.5 MeV. Total cross sections are given for 294.2, 299.5, 306.5, 314.3, and 319.5 MeV. The two angular distributions close to threshold are dominated by {ital s} wave contributions. Total cross sections within the first 30 MeV of threshold show qualitative agreement with an early theoretical prediction based on PCAC.

Abstract A two-arm spectrometer, designed to detect η and π 0 mesons, has been built and used in (π, η) measurements at LAMPE. This spectrometer contains BGO active converters and NaI total-energy counters. Its construction and performance for ( π − , π 0 ) and ( π − , η) measurements on CH 2 are described. Novel techniques to monitor the gains of the BGO an NaI counters are also presented.
