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 0- S resonance at 1.24 GeV with a width 0.36 GeV. The data also suggest the presence of another 0- S resonance of similar width near 1.8 GeV. These observations can be interpreted as radial excitations of the meson.
