Abstract: (Elsevier)

It is shown that the approximation of the narrow widths of the α 0 and a 0 resonances, that is used in both theoretical and experimental investigations of the radiative decays Φ → γa 0 and Φ → γα 0 , is not valid. It is explained how to correct take into account corrections for finite widths.
