The KLOE experiment at the electron-positron collider DAPHNE has collected in the 2001-2002 running period an integrated luminosity of 450 pb-1. Through the radiative {phi} decays, large samples of the light scalar mesons f0(980) and a0(980) are available. The f0 meson is clearly observed in {pi}+{pi}- and {pi}0{pi}0 final states, the a0 in the {eta}{pi}0 final states. Invariant mass spectra and Dalitz plot densities are analyzed to investigate the controversial structure of these particels.
