Abstract
A search for K(s)0 --> e+e- decay was performed by means of a 624-chan nel lead glass shower hodoscope and a set of proportional chambers. Ne utral kaons were obtained in the quasibinary charge exchange reaction. A new upper limit of 2.8 x 10(-6) at 90% C.L. for the branching ratio is obtained.
