Abstract
Using a sample of events collected with the CLEO II detector at the Cornell Electron Storage Ring, we have measured the form factors for . We perform a three-parameter fit with the joint distribution of four kinematic variables to obtain the form-factor ratios and and the form-factor slope which is closely related to the slope of the Isgur-Wise function. The form-factor ratios are consistent with predicted corrections to the heavy-quark symmetry limit .
