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 MeVc 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
