Partial widths for the decays $\eta(1295) \to \gamma\gamma$ and $\eta(1440) \to \gamma\gamma$

We discuss gamma gamma partial widths of pseudoscalar/isoscalar mesons eta(M) in the mass region M = 1000-1500 MeV. The transition amplitudes eta(1295) -> gamma gamma and eta(1440) -> gamma gamma are studied within an assumption that the decaying mesons are the members of the first radial exci...
