The results on spectra of negative particles produced in16O+Au and p-Au collisions at 200 GeV/nucleon and16O+Au at 60 GeV/nucleon are presented. The correlations of average rapidity and average transverse momentum with event multiplicity are studied. Spectral shapes are similar for central16O+Au and p-Au collisions. The transverse momentum and rapidity distributions for central16O+Au and p-Au collisions differ strongly from corresponding distributions for p+p interactions. The FRITIOF model fails to describe the shapes of the transverse momentum distributions. The simple thermodynamical model of a single fireball does not fit the midrapidity transverse momentum distributions, and the rapidity distributions.
