We report a measurement of the radiative decay of the K*- (890). The width for the transition K*- → K- γ is 62 ± 14 keV. The resulting ratio of decay probabilities (K*0 → K0γ)/(K*- → K-γ), while consistent with predictions of certain quark models, does not agree with expectations from unbroken SU(3) symmetry.
