Cumulative production of nucleons and extremely light nuclei in 4Hep interactions at an incident momentum of 5 GeV/c

The invariant cross sections for the cumulative production of protons, neutrons, and extremely light nuclei (d, ³H, and ³He) are determined on the basis of experimental data obtained by exposing the 2-m liquid-hydrogen bubble chamber of the Institute of Theoretical and Experimental Physics (ITEP, Moscow) to a 5-GeV/c α-particle beam, the kinetic energy of primary protons in the rest frame of the nucleus involved being T _p = 620 MeV. The results obtained in this way are compared with the predictions of the Frankfurt-Strikman model, which takes into account short-range few-nucleon correlations, and with the predictions of the nuclear coalescence model.
