AB  - A search is performed for a state X decaying into D^*0D̅^*0 produced in the process e^+e^−→γX using a data sample corresponding to an integrated luminosity of 1667.4 pb^−1 collected at √s = 4.682 GeV with the BESIII detector at the BEPCII. The state X could be one of the C-even states X(4013), η_c(3S), χ_c0(3P), χ_c1(3P), or χ_c2(3P). No significant signal is observed in the corresponding signal region. Upper limits of σ_e^+e^−→γX· Br_X→ D^*0D̅^*0 at 90% confidence level are provided, where σ_e^+e^−→γX represents the cross section of the e^+e^−→γX process, and Br_X→ D^*0D̅^*0 is the branching fraction of the X→ D^*0D̅^*0 process.
