Although 9-v' mixing is qualitatively well understood as a consequence of the IT( anomaly in QCD together with a broken SU(3)p flavor symmetry, until recently the values of decay and mixing parameters of the q and q' were only approximately known, e.g. values for the octet-singlet mixing angle betwe
