Abstract

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