Abstract: (Elsevier)
The change asymmetry in semi-leptonic kaon decays has been measured as a function of the kaon lifetime. High statistics data of K e3 0 and K μ3 0 decay modes agree with each other and with the general expectation of the CP violation phenomenology together with the ΔS − ΔQ rule. The K L -K S mass difference obtained is Δm = (0.533 ± 0.004) × 10 10 s −1 .
