We study the problem of pseudoscalar mixing in an (Formula presented) breaking framework. In this connection, we derive the condition of a vanishing (Formula presented) component in the η,(Formula presented) wave functions. We also obtain new constraints obeyed by the mixed decay constants (Formula presented) which determine the octet-singlet mixing angles. In the (Formula presented) sector we find from a fit to the radiative decay rates of mesons that the presence of a (Formula presented) admixture in (Formula presented) is small in disagreement with the point of view that the branching ratio of (Formula presented) is enhanced by (Formula presented) mixing. © 1999 The American Physical Society.
