Abstract

The Kloe experiment has measured the radiative decays of the phi meson into pi(0), eta and eta'(958),these measurements are relevant to assess' the mixing in the pseudoscalar nonet as well as to evaluate the gluon content in the eta'(958). Moreover also the radiative decays into pi(0)pi(0)gamma and etapi(0)gamma have been measured. These decays axe dominated by the final states f(o)(980) and a(o)(980). The measurement of the branching ratios and of the pi(0)-pi(0) or eta-pi(0) invariant mass spectrum helps to understand the controversial nature of the above scalar mesons.
