Primakoff production of the K0*(896) by incident KLs was observed in the energy range 100 200 GeV. Production from Cu and Pb targets was measured simultaneously leading to a new value for the K0*(896) radiative width (K0*(896)'K0+) of 116.59.9 keV. The result agrees with a previous determination while being considerably more precise and allows for more stringent tests of quark-model relations among the radiative widths of the low-lying vector mesons.
