Measurement of the analyzing power of the charge-exchange [formula omitted] reaction in the momentum range 546-875 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 pr...

Description
Summary: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.
