P̄-p Elastic scattering at 8 and 16 GeV/c

View publication


Angular distributions are presented for p̄-p elastic scattering at 8 and 16 GeV/c for |t|<1.3 (GeV/c)2. At both energies there is structure in the differential cross sections in the region 0.5<~|t|<~1.0 (GeV/c)2, similar to that observed at lower energies. The diffraction peak continues to expand with increasing incident momentum. © 1969 The American Physical Society.
