Abstract
Using a sample of integrated luminosity 1.68 fb-1 collected with the C LEO-II detector at the Cornell Electron Storage Ring, we measure the b ranching ratios for the dominant exclusive semileptonic decays D --> K lnu and D --> Klnu, using charged and neutral D mesons. We also make a precise measurement of the vector form factor for the decay D0 --> K -l+nu, using a sample of 2700 events.
