摘　　要：We discuss the production of ηc （2S） through the process e＋e- -→γηc （2S）, where the leading contributionoriginates from l-loop electroweak corrections. Adopting some reasonable light-cone distribution amplitudes, we analyze the cross section of this process. As the electron-positron center of mass energy √s=3770 MeV, the typicalproduction cross section of this process is about 1 fb.We discuss the production of ηc （2S） through the process e＋e- -→γηc （2S）, where the leading contributionoriginates from l-loop electroweak corrections.
