We have observed muons produced directly in Cu and W targets by 300-GeV incident protons. We find a yield of muons which is approximately a constant fraction (0.8·10−4) of the pion yield for both positive and negative charges and for transverse momenta between 1.5 and 5.4 GeV/c.

Differential cross sections as a function of transverse momentum are presented for the production at ∼90° (in the c.m. system) of π±, K±, p, and p¯ in p-nucleus collisions at incident proton energies of 200 and 300 GeV.

An experiment was done in the external proton beam of the Berkeley 184-in. cyclotron to measure the production cross sections for pions from various target nuclei, from hydrogen to lead. The cross-section data are presented and the reaction mechanisms discussed. The hydrogen production appears to fit the one-pion-exchange model.

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.
