Abstract

Employing the decay chain K+'+0, 0e+e- we have observed the decay 0e+e-. With a signal sample of 21 events we measure the branching ratio for 0e+e- to be (6.92.30.6)×10-8, normalized to the decay K+'+0, 0e+e-. This result is consistent with the unitarity lower bound and the published 90% confidence level upper limit of 13×10-8.
