π0 and η spectra from\(p\bar p\) annihilations at rest

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The low-energy part of theπ 0 spectrum associated with\(p\bar p\) annihilation at rest was measured in order to search for bound baryonium-like states. The upper limit for reaching such states via the emission of monochromaticπ 0's was found to be 8% per annihilation in the mass region of 1650 MeV. The low-energy part of the η spectrum from\(p\bar p\) annihilations at rest was also observed.
