Results of a simultaneous analysis of data from the KLOE detector (Italy) on the decay {phi} {sup {yields} {pi}0{pi}0{gamma}} and data on {pi}{pi} scattering and on the reaction {pi}{pi} {sup {yields}}KK-bar are presented. These data are described with allowance for the chiral shielding of the {sigma}(600) meson. The results favor the four-quark nature of the {sigma}(600) and f{sub 0}(980) mesons.
