Description
Momenta of charged particles produced in inelastic αα, αp, and pp collisions were measured using the Split-Field-Magnet detector at the CERN Intersecting Storage Rings. Inclusive and semi-inclusive spectra are presented as a function of rapidity y, Feynman-x, and transverse momentum psub(T). The inclusive y distributions agree well with predictions of the dual parton model; the highest particle densities are reached at yapprox.=0 and the momenta of leading protons decrease significantly for increasing total multiplicity. ''Temperatures'' are equal in αα, αp, and pp interactions. The psub(T) distributions depend weakly on the multiplicity. (orig.)
