Reanalyzing the-S-wave (TrTr)i=0 and (KTr)I=l/2 phase shifts through a new S-matrix parametrization method, the existence of a(600) and n(900)-particles is suggested, respectively. These particles have plausible properties as the members of scalar nonet, appeared as partners of pseudoscalar 7r-nonet
