| dc.description | We produce a sample consisting of 147 candidate events, with minimal backgrounds, of the mixed axial vector pair K1(1270)-K1(1400) by exciting Kl's in the Coulomb field of lead and report the first measurements of the radiative widths Gamma_r(K1(1400)) = 280.8+-23.2(stat)+-40.4(syst) keV and Gamma_r(K1(1270)) = 73.2+- 6.1(stat)+-28.3(syst) keV. We also place 90% CL upper limits Gamma_r(K*(1410)) < 52.9 keV for the vector state and Gamma_r(K2*(1430)) < 5.4 keV for the tensor state. These measurements allow for significant tests of quark-model predictions of radiative widths for the low-lying vector mesons. | |
