- Using an e thorn e- collision data sample of o27.08 ⠂ 0.14 thorn x 108 & psi;o3686 thorn events collected by the BESIII detector, we report the first observation of & chi;cJ & RARR; & omega;- over bar & omega; thorn (J 1/4 0, 1, 2) decays with significances of 5.6 & sigma;, 6.4 & sigma;, and 18 & sigma;, respectively, where the & chi;cJ mesons are produced in the radiative & psi;o3686 thorn decays. The branching fractions are determined to be Bo & chi;c0 & RARR; & omega;- over bar & omega; thorn thorn 1/4 o3.51 ⠂ 0.54 ⠂ 0.29 thorn x 10-5, Bo & chi;c1 & RARR; & omega;- over bar & omega; thorn thorn 1/4 o1.49 ⠂ 0.23 ⠂ 0.10 thorn x 10-5, and Bo & chi;c2 & RARR; & omega;- over bar & omega; thorn thorn 1/4 o4.52 ⠂ 0.24 ⠂ 0.18 thorn x 10-5, where the first and second uncertainties are statistical and systematic, respectively.
