(p,2p) study of high-momentum components at 2. 1 GeV

A (p,2p) experiment designed to isolate interactions with small numbers of fast nuclear constituents is described. Special attention is paid to the experimental manifestation and description of a correlated pair of nucleons in the nucleus. Phase space calculations are presented for the proton-pair three-body final state and for final states with larger number of particles. The Two Armed Spectrometer System (TASS) is described in detail. The data suggest the possibility of isolating an interaction with one or two nucleons in the nucleus which may have momenta far in excess of those described in a Fermi gas model

Observation of high-momentum protons from limiting target fragmentation

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
