          <dc:description>Charmonium production in 190 GeV/c (pi)('-)-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 (+OR-) 0.09 of total J/(psi) production for J/(psi)'s with x(,f) &amp;gt; 0.2. The rate of production for the two (chi) states appears as B(sigma)((chi)(3555)/B(sigma)((chi)(3510) = 0.60 (+OR-) 0.35. The fraction of J/(psi)'s produced through (chi) decay appears to rise with higher x(,f). For J/(psi)'s with x(,f) &amp;gt; 0.42, (chi) decay is responsible for 0.345 (+OR-) 0.09 of the total J/(psi) sample, with the two states produced at the rate B(sigma)((chi)(3555)/B(sigma)((chi)(3510) = 0.82 (+OR-) 0.45.</dc:description>
