摘要：

The cross section for 180 °elastic scattering of antiprotons by protons between 406 and 922 MeV/c has been measured. A single-arm spectrometer detected recoil protons corresponding to events with cosθc.m. =-0.994. The regions of the reported resonances at 1936 and 2020 MeV were scanned in 10-MeV/c steps with a typical statistical error of 7% and an rms mass resolution of ±3 MeV. No narrow enhancements (Γ<10 MeV) were observed. © 1979 The American Physical Society.
