摘要：

We report on chi(c1) and chi(c2) production in the Feynman:x range 0.1 < x(F) < 0.8 in 515 GeV/c pi(-)Be collisions. The chi(c) states are observed via their radiative decays into J/psi's. The resulting photons are detected tither as showers in the electromagnetic calorimeter or after conversion in the target as e(+)e(-) pairs in the tracking system. The fraction of J/psi production due to chi(c1) and chi(c2) decays is 0.443 +/- 0.041 +/- 0.035. The ratio of the chi(c1) to chi(c2) cross section is 0.57 +/- 0.18 +/- 0.06. Our results on J/psi, psi(2S), and chi(c) production indicate that 0.454 +/- 0.034 +/- 0.042 of J/psi's are produced directly.
