• Non-leptonic interactions in the current-current interaction are examined and criticized. By using a Born (factorization) approximation, it is concluded that the pure ΔI=3/2 process, i. e. the K^+→π^++π^0 decay can be caused with strength about 20 times greater than the observed value and that the ΔI=1/2 processes are, on the contrary, caused only partially (1/20~1/50) irrespective of the process (hyperonic or mesonic) and of the presence or absence of parity conservation in the transition. It is also pointed out that this universal character of "theoretical" suppression for the ΔI=1/2 processes is due almost directly to the unwanted factor cos^2θsin^2θ. A new two-body interaction of leptons and a corresponding non-leptonic interaction with ΔI=1/2 is discussed.
