Abstract
We discuss partial widths of pseudoscalar/isoscalar mesons in the mass region MeV. The transition amplitudes and are studied within an assumption that the decaying mesons are the members of the first radial excitation nonet . The calculations show that partial widths being of the order of 0.1 keV are dominantly due to the meson component while the contribution of the component is small.
