Resumen

Using data samples with an integrated luminosity of 4. 67~fb^-1 collected by the BESIII detector operating at the BEPCII collider, we search for the process e^+e^- ' (2S) at center-of-mass energies from 4. 66 to 4. 95~GeV. No significant signal is observed, and upper limits for the Born cross sections B (e^+e^-' (2S) ) at the 90\% confidence level are determined.
