Abstract : No examples of the decay 'neutral-eta to neutral-pion + positron + electron' were found in a sample of film containing 387 detected 'neutral-eta to neutral-pion + positive-pion + negative-pion. The film was taken with the Ecole Polytechnique heavy liquid bubble chamber exposed to 950 MeV/c negative-pions at Saclay. With 90% confidence the branching ratio to 'neutral-eta to neutral-pion + positron + electron is less than 0.23% of all neutral-eta baryons decays. (Author)
