摘要：

An attempt to extend chiral perturbation theory to radiative vector meson decays into two neutral pseudoscalars, V0 --> P0P0-gamma, is presented. The effects of (chiral) loops are found to be important. Unambiguous predictions are given for phi-->pi-0-pi-0-gamma, pi-0-eta-gamma, rho --> pi-0-pi-0-gamma and other processes to be measured in proposed low-energy e+e- machines.
