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 mea

✦ Synopsis
The KLOE experiment at the DA~NE C-factory has just started collecting data. One of the first analysis items is the study of the ¢ radiative decays, which allows us to investigate the nature of light pseudoscalar and scalar mesons. An integrated luminosity of 100 pb -1 is expected for next KLOE run, resulting in 3 x 10 s ¢ collected. A detailed simulation and full event reconstruction of both signal and background events indicates a sensitivity reach of 1 -2% on the branching ratios. Some preliminary studies on real data are also presented, showing a good agreement with MonteCarlo distributions.
