Description

Partial wave analysis has been performed on 120.000 π-π-π+ events coherently produced on nuclear targets in a π- beam of 40 GeV/c. Evidence has been found for an O-S resonance at 1.24 GeV with a width GAMMAroughly-equal0.36 GeV. The data also suggest the presence of another O-S resonance of similar width near 1.8 GeV. These observations can be interpreted as radial excitations of the π meson
