In this study, by analyzing a data set of 2.92 fb-1 of e+e- collision data taken at ps = 3.773 GeV and 106.41×106 ψ(3686) decays taken at √s = 3.686 GeV with the BESIII detector at the BEPCII collider, we measure the branching fraction and the partial decay width for ψ(3770) → γχc0 to be B(ψ(3770) → γχc0) = (6.88 ± 0.28 ± 0.67) × 10-3 and Γ[Ψ(3770) → γχc0] = (187 ± 8 ± 19) keV, respectively. These are the most precise measurements to date.
