Two mixing angle description of radiative VPγ decays

An analysis of various radiative VPγ decays is performed using the two mixing angle description of the η−η′ system. The agreement is excellent. Our results are expressed both in the “octet-singlet” and in the “quark-flavour” basis. It turns out that at the present experimental accuracy, the two angles are significantly different in the former, but not in the latter basis.
