Final results of the measurement of the analysing power A On of the p p → n n reaction are presented. Eight measurements in the range 546–1287 MeV/ c incoming p momentum have been performed over the full angular range using a solid polarized proton target and the Low Energy Antiproton Ring (LEAR) at CERN antiproton extracted beams.

Measurement of the analyzing power of the charge exchange anti-p p ---> anti-n n reaction in the momentum range 546-MeV/c - 875-MeV/c at LEAR

Results are given for the analysing power of the p ̄ p→ n ̄ n charge-exchange reaction at four incident beam momenta. The measurement is part of an experimental programme to study the spin structure of this reaction at LEAR. The analyzing power shows strong angular and energy dependence, which at present is not reproduced by the existing meson-exchange potential models.
