Abstract：
The data collected by the KLOE Collaboration at the Frascati φ-factory DAΦNE from 2001 to 2006 have been used for extensive studies in meson spectroscopy. The decays of the scalar mesons a₀(980) and f₀(980) into two pseudoscalar mesons have been exploited to measure the relevant parameters of those resonances. The radiative decays φ→ηγ and η′γ have been used for the determination of the pseudoscalar mixing angle and to search for a possible gluonium content in the η′. The dynamics of the η→3π decay has been studied and the Dalitz Plot parameters have been measured. The large amount of η mesons produced allowed also to study interesting rare η decays.
