Abstract
We present measurements of , where or , and is the photon energy in the kaon rest frame. These measurements are based on decays collected in 1997 by the KTeV (E832) experiment at Fermilab. With samples of 1385 and 14221 candidates, we find and . We also examine distributions of photon energy and lepton-photon angle.
