Abstract
Interactions of 209-GeV muons in the multimuon spectrometer at Fermilab have yielded 20 072 dimuon final states, with (81±10)% attributed to production of charmed states decaying to muons. The cross section for diffractive charm muoproduction is nb. Extrapolated to , the effective cross section for 178- (100-) GeV photons is () nb.
