Résumé
Production and decay into two muons of ψI and J/ψ mesons is studied in p-U and S-U interactions at 200 GeV/nucleon. The ratio Bmumuσ(ψl)/Bmumuσ(J/ψ is found to be 0.0201 ± 0.0044 ± 0.0020 in p-U and 0.0093 ± 0.0011 ± 0.0013 in S-U. For S-U interactions, this ratio decreases by about 40% with increasing transverse energy. Our p-U result confirms previous measurements which show that the relative production of ψt and J ψ in p-A interactions is independent of A. The results are discussed in the frame of QGP formation and final state absorption.
