Differential cross sections as a function of momentum are presented for the production of π mesons, K mesons, protons, deuterons, tritons, and He3 at various laboratory angles by 2.9-BeV protons striking Be and Pt targets. The Be data were taken at 13°, 30°, 60°, and 93° relative to the direction of the Princeton-Pennsylvania Accelerator internal proton beam; the Pt data were taken at 13° and 93° only. The results are compared with the corresponding data in hydrogen in order to investigate the role of the complex nucleus in particle production at this energy.

Detailed measurements of the production of charged π mesons in proton-proton collisions are reported. The observed results are compared with the "isobar" and "one-pion exchange" models and for single production are in agreement if only the "resonant" part of the π−p cross section is used and if the angular distribution cos16θ is introduced for the production of the N1* isobar. The effects of higher resonances are also considered.
