Abstract
The Feynman-Dyson formalism is applied to the calculation of multiple π 0-production in proton-antiproton annihilation. The calculations are along lines very similar to those recently followed by Gupta. It is found that contrary to the corresponding results of Quantum Electrodynamics, the cross section for the multiple production of π 0's begins to decrease only for values of n > 15. Since each π 0 decays into two photons almost immediately, the bearing of this result on the Schein event is briefly discussed.
