Abstract

We use [Formula presented]’s in the 100–200 GeV energy range to produce 147 candidate events of the axial vector pair [Formula presented] in the nuclear Coulomb field of a Pb target and determine the radiative widths [Formula presented] and [Formula presented]. These first measurements appear to be lower than the quark-model predictions. We also place upper limits on the radiative widths for [Formula presented] and [Formula presented] and find that the latter is vanishingly small in accord with SU(3) invariance in the naive quark model.
