Popis: The chi /sub 1//sup ++/(3507) and the chi /sub 2//sup ++/(3553) states have been observed in the Goliath spectrometer at the CERN SPS in 185 GeV/c\pi^{-}-Be collisions. Their radiative decays contribute 27.7% (for the chi /sub 1//sup ++/) and 12.8% (for the chi /sub 2//sup ++/) to J/ psi production. At this energy, their cross sections are 65+or-19 nb and 96+or-29 nb, respectively.
