We are studying production of χ c states in 530 GeV/c π− interactions with several targets. χ c mesons are observed in the mode (χ→J/ψ+γ). Only photons that converted to e + e − pairs are used in the reconstruction of the χ c mesons. Preliminary analysis shows that the fraction of observed J/ψs coming from χ c radiative decays is 0.44±0.09±0.08, and that the relative production rate of χ c1 to χ c2 is 1.3±0.6.
