摘要：

Psi' and J/Psi yields are compared in p-W, p-U and S-U interactions at 200 GeV/nucleon. Their ratio decreases from proton-to sulphur-induced reactions. it also decreases in sulphur-induced reactions from peripheral to central collisions. This result could indicate that the Psi' and J/Psi suppression mechanisms have different origins in p- and S-induced reactions.
