Abstract
It is shown that the approximation of the narrow widths of the f(0) an d a(0) resonances, which is used in both theoretical and experimental investigations of the radiative decays phi --> gamma a(0) and phi --> gamma f(0), is not valid. We will explain that there is a need to take into account the corrections for finite widths.
