Charmonium production in 190 GeV/c /sup + -/-Be interactions has been observed. The states chi(3510) and chi(3555) are seen through their radiative decay into J/psi, and are found to correspond to 0.29 +/- 0.09 of total J/psi production for J/psi's with x/sub f/ > 0.2. The rate of production for the two chi states appears as Bsigma(chi(3555)/Bsigma(chi(3510)) = 0.60 +/- 0.35. The fraction of J/psi's produced through chi decay appears to rise with higher x/sub f/. For J/psi's with x/sub f/ > 0.42, chi decay is responsible for 0.345 +/- 0.09 of the total J/psi sample, with the two states produced at the rate Bsigma(chi(3555)/Bsigma(chi(3510)) = 0.82 +/- 0.45.
