The radiative widths for the mixed axial vector pair K1(1270)-K1(1400) were measured using the Primakoff effect. An upper limit was placed on the radiative width for K*(1410). These radiative widths were studied for the first time. Furthermore, it was found that the radiative width for K2*(1430) is vanishingly small, as anticipated on the basis of SU(3) invariance in the naive quark model.
