We examine effects of final state interactions (FSI) in kaon decays using a
new scheme without the Omnes function, and show that while Delta I=1/2 rule is
impossible to be explained in terms of FSI alone, ϵ′/ϵ∼16.5×10−4 is obtained through FSI, if the calculation is concerned
only with the CP-violating parts. The pi-pi contribution to the m_L-m_S mass
difference is shown to be about 0.14, if the sizes of the CP conserving
amplitudes A_0 and A_2 are correctly given.Comment: 6 pages and 2 eps figures, LaTeX
