Abstract
It is shown that the approximation of the narrow widths of the f(0) an d a(0) resonances, that is used in both theoretical and experimental i nvestigations of the radiative decays phi --> gamma a(0) and phi --> g amma f(0), is not valid. It is explained how to correctly take into ac count corrections for finite widths.
