Measurement of $\psi$ (3.1) Meson Production by Pions and Protons

The production of ψ(3.1) mesons is reported for the reactions π−+Fe→μ++μ−+anything, at 200 GeV, and p+Fe→μ++μ−+anything, at 240 GeV. For ψ production, distributions in x≡PLPbeam and P⊥ are given. For x>~0.5, the ratio of the ψ production cross sections in iron for pions to that for protons is found to be 7.4±2.0.
