摘要：

Muon-pair production has been measured in p-Cu, p-U, O-Cu, O-U and S-U collisions at 200 GeV per nucleon. The cross sections are compatible with the atomic number dependence (A(proj.)A(targ.))alpha where alpha = 0.91 +/- 0.04 for the J/psi-resonance and alpha = 1.01 +/- 0.04 for muon pairs produced in the mass continuum between 1.7 and 2.7 GeV/c2.
