英文摘要DAPhiNE (Double Annular Phi-factory for Nice Experiment) is the Fraseati(Italy) electron positron collider operating at the energy of 510 MeV, a rather low energy with respect to the other existing factories. DAPhiNE includes two collision points, and KLOE detector is located at one of these points. The KLOE detector is designed primarily for the goal of detecting direct CP violation in KO decays with a sensitivity of similar to 10(-4) in R (epsilon'/epsilon), with a vast amount of other physics subjects. radiative dacays, especially its pure neutral final states are very important subjects to test the Chiral Perturbation Theory approach both in the anomalous and non-anomalous sectors. In this paper, a new kinematic fit method-TELESIS-is used for the data analysis of phi radiative decay phi-->gammaeta-->3gamma and phi-->gammapi(0)-->3gamma based on a part of 2000' data collected by KLOE detectors in DAPhiNE, the phi produced cross section and the partial cross section of e(+)e(-)-->phi-->gammapi(0)-->3gamma have been obtained as follows: sigma(e+e--->phi) = (4.04 +/- 0.04 +/- 0.24) mub, sigma(e+e--->gammapi0-->3gamma) = (5.3 +/- 0.3 +/- 0.6) nb. These results are in good agreement with that of VEPP and theoretical predictions.
