Abstract
Recent p+A..-->..p+X data are analyzed within the context of the multichain and additive quark models. We deduce the average energy loss of a baryon as a function of distance traversed in nuclear matter. Consistency of the multichain model is checked by comparing the predictions for p+A..--> pi../sup + -/+X with data. We discuss the space-time development of baryon stopping and show how longitudinal growth limits the energy deposition per unit length. Predictions are made for the proton spectra to be measured in nucleus-nucleus collisions at CERN and BNL. Finally, we conclude that the stopping domain for central collisions of heavy ions extends up to center-of-mass kinetic energies E/sub c.m./roughly-equal(3 +- 1)A GeV.
