摘要：
It is shown that the approximation of the narrow widths of the f(0) and a(0) resonances, that is used in both theoretical and experimental investigations of the radiative decays phi --> gamma a(0) and phi --> gamma f(0), is not valid. It is explained how to correctly take into account corrections for finite widths.
