Resolution of theT=0Fermi-Yang Ambiguity inK-Nucleon Scattering

Abstract
From an exposure of the BNL 30-in. deuterium-filled bubble chamber to a 600-MeV/c K+ beam, the angular distribution (14 912 events) and polarization (853 double-scattered events) for the charge-exchange reaction have been obtained. The results of partial-wave analyses of the data indicate the dominance of a positive P12 phase shift, and consequently establish a T=0 Yang-type solution.
