Abstract

The annihilation fractions and cross sections for the np annihilation reaction in flight (~ 50-400 MeV/c) into ηπ⁺ and η'π⁺ final states have been measured. The first ones follow the trend expected for P wave annihilations. From the ratios of the yields an evaluation of the pseudoscalar mixing angle in the standard form is possible. The value found shows that for pseudoscalar meson production from P wave the Quark Line Rule is not grossly violated. (C) 1999 Elsevier Science B.V.
