High-multiplicity events were selected in collisions of 800 MeV per nucleon Ar on KCl and Pb. In these events projectile fragments are highly suppressed, and the angular distributions of high-energy protons are almost isotropic in a moving frame whose rapidity is y{sub 0} ( y{sub 0} ~ 0.60 for KCl and 0.43 for Pb targets). Comparisons with inclusive proton data are used to estimate the relative importance of single and multiple NN collisions. Pion spectra in high-multiplicity events are also presented.
