By taking into account the tadpole contribution we restore the chiralproperties of the amplitude /ital K//sub /ital S// (/ital p//sub /ital K//)/r arrow/..pi..(/ital p//sub ..pi../ )+..pi..(/ital p//sup '//sub ..pi../) calculated by thevacuum-insertion method, which leads to the replacement of themomentum-independent part of the amplitude by the term (2/ital F//sub ..pi..//ital F//sub /ital K// )/sup /minus/1/<0/vert bar/H /sup weak//vert bar//ital K//sub /ital S//(0)/gt//ital p//sup 2//sub /ital K////ital m//sup 2//sub /ital K//.As a consequence of this, a part of the physical amplitude can beexpressed directly in terms of the amplitude<0/vert bar/H /sup weak//vert bar//ital K//sub /ital S//(0)>.
