We have studied semileptonic B meson decays with a p-wave charm meson in the final state using 3.29×106 BB̅ 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 B(B-→D10ℓ-ν̅ ℓ)B(D10→D*+π-) = (0.373±0.085±0.052±0.024)% and an upper limit for B(B-→D2*0ℓ-ν̅ ℓ)B(D2*0→D*+π-)<0.16% (90% C.L.). Furthermore, we present the first measurement of the q2 spectrum for B-→D10ℓ-ν̅ ℓ.
