For the weak nonleptonic decay K..-->..3..pi.., we analyze the amount of CP violation expected to arise in the Kobayashi-Maskawa model using two recently uncovered aspects: (1) quadratic terms in the K..-->..3..pi.. amplitude (found in the CP-conserving data) and (2) electromagnetic and isospin-breaking effects in the relation of the CP-violating parameters of K..-->..2..pi.. and K..-->..3..pi... Previous to the inclusion of these effects the non-epsilon signal in eta/sub +-0/ (eta/sub +-0/ = epsilon+epsilon/sub +-0//sup '/) required interference with the highly suppressed ..delta..I = (3/2 amplitude; however in the present analysis the epsilon/sub +-0//sup '/ signal is not suppressed. We estimate values for epsilon/sub +-0//sup '/ about an order of magnitude larger than previously anticipated, although still smaller than epsilon.
