Abstract
We have studied semileptonic meson decays with a -wave charm meson in the final state using events collected with the CLEO II detector at the Cornell Electron-Positron Storage Ring. We find a value for the exclusive semileptonic product branching fraction and an upper limit for (90% C.L.). Furthermore, we present the first measurement of the spectrum for .
