Peripheral Anti Pn Production and Decay Angular Distributions in the Reaction pi exp - p Implies (Anti Pn)p at 12 GeV/C Incident Momentum

摘要

The reaction pi exp - p implies (anti pn)psub(s), where psub(s) is a slow proton, was measured at 12 GeV/c incident momentum with the CERN-OMEGA spectrometer. Both antiproton and proton were identified uniquely by electronics information. We obtained 1844 events with four-momentum transfer squared in the range 0.13
