    Observation of high-momentum protons from limiting target fragmentation

    No full text
    Measurements of the inclusive distributions of protons produced at 180{sup o} in the momentum range 0.3 {le} p {le} 1.0 GeV/c are reported. Proton, {alpha}-particle, carbon, and argon beams in the range of kinetic energies 0.4 {le} T {le} 2.1 GeV/nucleon (4.89 GeV for protons) were incident on C, Al, Cu, Sn, and Pb targets. The dependences of the cross sections on the projectile and target mass and on the incident energy are presented. Limiting behavior is found at energies above 1-2 GeV/nucleon. Features suggestive of nuclear correlations are discussed
