The differential cross section of the charge-exchange reaction p p → n n has been measured at the CERN Low Energy Antiproton Ring (LEAR) at seven p momenta in the range 546–1287 MeV/ c . A pentanol polarized target has been used and the neutron and the antineutron have been detected in coincidence. The data cover most of the angular range.

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.
