英文摘要A search is performed for the production of the psi(2S) in e(+)e(-) annihilation at a center-of-mass energy of 4.03 GeV using the BES detector operated at the Beijing Electron Positron Collider (BEPC). The kinematic features of the reconstructed psi(2S) signal are consistent with its being produced only in association with an energetic photon resulting from initial state radiation (ISR). Limits are placed on psi(2S) production from the decay of unknown charmonia or metastable hybrids that might be produced in e(+)e(-) annihilations at 4.03 GeV. Under the assumption that the observed cross section for psi(2S) production is due entirely to ISR, the partial width Gamma(ee) of the psi(2S) is measured to be 2.07+/-0.32 keV.
