Query: Study of $B^{-} \to D_{2}^{*}(2460)^{0} \pi^{-}$ and $B^{-} \to
  D_{1}(2420)^{0} \pi^{-} $ Decays   We report on a study of $B$ mesons decaying into one of the narrow P-wave
charm resonances, $D_2^{*}(2460)^{0}$ and $D_1(2420)^0$. Our preliminary
results are based on 89 million \BB pairs collected with the \babar detector at
the PEP-II asymmetric $B$ Factory. Our study will be useful in the
investigation of the properties of Heavy Quark Effective Theory.
