We present evidence for the existence of two new I=0 scalar mesons [gs(1240) and S*′(1730)] from an amplitude analysis of the reaction π-p→KS0KS0n at 23 GeV/c. An examination of the mass splittings present shows that neither of these states can be easily assigned to a (near) ideally mixed JPC=0++ nonet. These results are in qualitative agreement with recent theoretical predictions of glucon-glucon bound states.
