Determination of the $η$-$η^\prime$ mixing angle

We extract $η$-$η^\prime$ mixing angle and the ratios of decay constants of light pseudoscalar mesons $π^0$, $η$ and $η^\prime$ using recently available BaBar measurements on $η$-photon and $η^\prime$-photon transition form factors and more accurate experimental data for the masses and two-photon decay widths of the light pseduoscalar mesons.
