Using infinite-momentum-frame techniques we generalize the Schwinger formula for the pseudoscalar nonets to include the effects of the (1460). By seeking consistency with its current rates we estimate the (1460) mixing angles. We also allow the possibility of nonet symmetry breaking in the couplings. Our results support a glueball interpretation of the with not inconsistent with quarkonium states. © 1988 The American Physical Society.
