The study of the I=1, 0{sup ++} states with the OBELIX detector in the channel p-barp{yields}K{sup {+-}}K{sub S}{sup 0}{pi}{sup {+-}} at three different target densities is reported. We discuss in particular the initial state dependence of a{sub 0}(980) production and the evidence of an extra scalar state with mass 1.29{+-}0.01 GeV/c{sup 2} and width 0.080{+-}0.005 GeV/c{sup 2}.
