Abstract

The relative probability distribution of π ±and π 0 mesons in pp annihilation was measured in 10 MeV bins from 2.15 to 2.23 GeV. No significant variation in probabilities was found, and mean values are consistent with those reported at 2.28 GeV. Observed multiplicity distributions are consistent with two-body cascading on the statistical model under equal weighting of G = ±1 states.
