Abstract

The Kloe experiment has measured the radiative decays of the r$ meson into TO, 77 and q’(958); these measurements are relevant to assess the mixing in the pseudoscalar nonet as well as to evaluate the gluon content in the q’(958). Moreover also the radiative decays into #7r”y and 17~‘~ have been measured. These decays are dominated by the final states fo(980) and a(980). The measurement of the branching ratios and of the 7r” - r” or 7 - no invariant mass spectrum helps to understand the controversial nature of the above scalar mesons.
