Using a sample of 158 x 106 ?(2S) events collected with the Belle detector, charmonium and charmoniumlike states with even charge parity are searched for in ?(2S) radiative decays. No significant Xcl or nc signal is observed, and the following upper limits at 90% confidence level (C. L.) are obtained: ?(?(2S)?YXco)
