Abstract
The total cross section is ∼10% larger than the extrapolated cross section seen at higher (∼0.5-2.0 GeV/c) momenta. The excess is mainly due to the nonannihilation part of the total cross section. The annihilation cross sections in and are the same. These observations are consistent with known properties of the . A dip is present at ∼0.43 GeV/c mainly due to annihilation. This dip cannot be understood in terms of a single resonance at and the . Our cross sections are ∼10-20% higher than the recent measurements of Hamilton et al.
