Abstract
We have studied the production of J/psi, psi' and prompt muon pairs in the mass continuum from a sample of sulfur-uranium interactions at 20 0 GeV/c per nucleon. We report, in this letter, results obtained for t he transverse momentum distributions and their dependence on the trans verse energy released in the collision, used as an estimator of the ce ntrality of the nucleus-nucleus interaction.
