Abstract
Partial-wave analysis has been performed on 120 000 events coherently produced on nuclear targets in a beam of 40 GeV/c. Evidence has been found for a resonance at 1.24 GeV with a width GeV. The data also suggest the presence of another resonance of similar width near 1.8 GeV. These observations can be interpreted as radial excitations of the meson.
