摘要：

We report the first observation of chi(c2) production in B meson decays. We find an inclusive B-->chi(c2)X branching fraction of (1.80(-0.28)(+0.23)+/-0.26) x10(-3) . The data set, collected with the Belle detector at the KEKB e(+)e(-) collider, consists of 31.9x10(6) B (B) over bar events. We also present branching fractions and momentum spectra for both chi(c1) and chi(c2) production.
