Polarization asymmetry in the charge-exchange reactions. pi. /sup -/+p/sub up-arrow/. -->. eta(eta')+n

The usual scheme of SU(3) mixing of the octet and singlet components of the eta(549) and eta'(958) mesons is used to predict the relative sign of the polarization asymmetries in the charge-exchange reactions ..pi../sup -/p/sub up-arrow/..-->..eta(eta')n in the region of not very large chemically bondtchemically bond.
