Determine the rapidity and transverse momentum distributions of forward protons and neutrons in relativistic silicon-nucleus collisions to deduce in-medium nucleon-nucleon cross sections.
Directed 14.6 GeV/nucleon beams of silicon-28 at targets of aluminum, copper, and lead.
Measured proton and neutron kinematic distributions using the forward spectrometer and target calorimeter in the E814 experimental apparatus.
Compared experimental data against predictions from nuclear fragmentation models and heavy-ion particle-production models.
Observed two distinct kinematic domains: beam-rapidity projectilelike nucleons and participant nucleons.
Deduced that the in-medium inelastic nucleon-nucleon cross section agrees within 10% with the free value of 30 mb, despite a high probability of prior nucleon strikes.
