We show that instanton effects may play a crucial role in the decay of scalar
mesons into two pseudoscalars. Particularly the branching ratios of two meson
decays of the f0(1500), which is considered as a glue-ball candidate, are
then compatible with an ordinary qqˉ-structure of this resonance and a
small positive SU(3) mixing angle, close to a result recently calculated with
the same instanton-induced force.Comment: 9 pages, uuencoded latex including two figure
