Abstract

Recently, highly relativistic Au beams have become available at the Brookhaven National Laboratory Alternating Gradient Synchrotron. Inclusive production cross sections for composite particles, d, t, He-3, andHe-4, in 11.5A GeV/c Au+Pt collisions have been measured using a beamline spectrometer. For comparison, composite particle production was also measured in Si + Pt and p + Pt collisions at similar beam momentaper nucleon (14.6A GeV/c and 12.9 GeV/c, respectively). The projectile dependence of the production cross section for each composite particle has been fitted to A(proj)alpha. The parameter alpha can be described by a single function of the mass number and the momentum per nucleon of the produced particle. Additionally, the data are well described by momentum-space coalescence. Comparisons with similar analysis of Bevalac A + A data are made. The coalescence radii extracted from momentum-space coalescence fits are used to determine reaction volumes (''source size'') within the context of the Sato-Yazaki model.
