Title: THE PARITY OF THE NEUTRAL PION AND THE DECAY pi{sup 0} Yields 2e{sup +} + 2e{sup -}

Abstract

Two hundred and six electronic decays of the pi{sup 0}, pi{sup 0} yields e{sup +} + e{sup -} + e{sup +} + e{sup -}, were observed in a hydrogen bubble chamber. The decay distributions of the electron pairs and the total rate for this process are shown to be in good agreement with theory. An examination of correlations of the e{sup +}e{sup -} pair decay planes on the basis of electrodynamic predictions is in agreement with the hypothesis that the pi{sup 0} is pseudoscalar, but disagrees for scalar pions by 3.6 standard deviations.
