Abstract

We have studied the reactions p+A→ (p, n)+X and p̄+A→p̄+X at beam momenta of 100 GeV/c for Mg, Ag and Au targets. The rapidity loss of the leading final state protons, antiprotons, and neutrons has been obtained as a measurement of the nuclear stopping power and correlated with the number of slow protons and the multiplicity and momentum of the associated charged particles.
