The HELIOS experiment has measured inclusivep⊥ spectra of negative particles in the rapidity region 1.0<y<1.9. The general shape of thep⊥ spectra in p +W, O+W and S+W is similar, but cannot be described by a single exponential. Compared to p+p collisions, an excess is observed for low and highp⊥. This effect increases with the projectile mass. Except for very lowE⊥, the average transverse momentum <p⊥> is found to be approximately constant up to the highest accessible values ofE⊥.
