  <dc:description>Using data samples collected at center-of-mass energies of √s = 4.009, 4.230, 4.260, and 4.360 GeV with the BESIII detector operating at the BEPCII collider, we perform a search for the process e+e− → γχcJ (J=0, 1, 2) and find evidence for e+e− → γχc1 and e+e− → γχc2 with statistical significances of 3.0σ and 3.4σ, respectively. The Born cross sections σB(e+e− → γχcJ), as well as their upper limits at the 90% confidence level (C.L.) are determined at each center-of-mass energy.</dc:description>
