Abstract
We present here experimental results on the annihilation of stopped antiprotons into , , and . We find the branching ratios for and to be (0.25±0.04) × and (1.08±0.16) × , respectively. From events of the latter reaction we find the width of the meson to be 12.3±2.0 MeV. The meson is observed and evidence is seen for the assignment of even charge conjugation and even parity to this resonance. In addition, we have used events from the reaction to measure the mass difference between the charged and neutral . We find MeV.
