Based on data samples collected with the BESIII detector at the BEPCII collider at nine center of mass energies from 4.21 to 4.42 GeV, we search for the production of e+e−→ωχcJ (J=0, 1, 2). The process e+e−→ωχc0 is observed for the first time, and the Born cross sections at s√=4.23 and 4.26 GeV are measured to be (55.4±6.0±5.9) and (23.7±5.3±3.5) pb, respectively, where the first uncertainties are statistical and the second are systematic. The ωχc0 signals at the other seven energies and the e+e−→ωχc1 and ωχc2 signals are not significant, and the upper limits on the cross sections are determined. By examining the ωχc0 cross section as a function of center of mass energy, we find that it is inconsistent with the line shape of the Y(4260) ob...
