Data taken in a Fermilab experiment designed to measure to CP-violation parameter μ/μ from a study of K'2 decays were used to look for the as yet unseen decay modes KL,S'0e+e-. The detector was optimized for the detection of kaon decays with four electromagnetic showers in the final state. The results (90% confidence) are branching ratios <4.2×10-8 and <4.5×10-5 for KL'0e+e- and KS'0e+e-, respectively.
