Abstract
The final state interactions of pions in decays Kππ0π0 are considered using the methods of quantum mechanics. We show how to incorporate the electromagnetic effects in the amplitudes of these decays and to work out the relevant expressions valid above and below the two charged pions production threshold Mc=2m. The electromagnetic corrections are given as evaluated in a potential model.
