Abstract

Inelastic interactions of 4He nuclei at the incident momentum of 4.5 GeV/c)/nucleon with pure Li, C, Al, Cu and Pb targets were studied in the SKM-200 streamer chamber. Cross sections and their dependence on the target mass number for fragmentation processes were obtained. The multiplicities, transverse momenta and rapidities of negative pions as well as their correlations were analyzed separately for “central” and “peripheral” collisions. A comparison of the results with the predictions of some theoretical models is presented.

    The phase space of interest for light ion production, which tests both coalescence and EMD improvements, is extremely large. The light ion database that was assembled consists of 386 cross-sections from 10 different publications [66,78,79,86,96,98–102]. The light ion data assembled herein sparsely populate the phase space of interest.
