The scalar meson exchange in 4 ----t P"Poy decays is discussed in a chiral invariant framework where the scalar meson poles are incorporated explicitly. 4 -+ z"7roy and Q -+ no777 are in agreement with recent experimental data and can be used to extract valuable information on the properties of fo(
