Summary We study the predictions for the axial couplings following from the use of the mixing operatorU(Z), previously introduced to tilt the axial charges ofSU 6 in the physical ones. The quantum number (−1) L+L 3, whereL andL 3 are theO 3 angular momentum and its third component, is shown to be conserved. From the properties ofZ further predictions can be achieved as theD/F=3/2 for the 1/2+ baryon octet in general agreement with experiment.
