We have measured the cross section for μ+μ- production in the reactions (π+, <FOR VERIFICATION>p)+Be→μ++μ-+X, at an incident momentum of 150 GeV/c. This Letter covers the pairs with masses above 2 GeV/c2, in which region the signal is dominated by production of the J(3.1). No events with μ-pair mass >4.1 GeV/c2 were seen, although the experiment is sensitive up to 12 GeV/c2.
