Abstract

p spectra of negative particles were measured for p–W and 16O–W collisions at 200 GeV/u in the rapidity range 0.9 < y < 1.9. Within the systematic errors of 20% the spectra are identical in the range 0.05<p <2.0 GeV/c. The p–W and 16O–W spectra exhibit an exponential shape for p >250 MeV/c. This is consistent with previous p — A data, but there is a significant excess above this exponential at lower p . Photon spectra were measured using a conversion method. Their p distribution agrees in shape with the sum of known hadronic γ-sources.
