| dc.description | Using 226 million $B\bar{B}$ events recorded on the $Υ(4S)$ resonance with the BABAR detector at the SLAC $e^+e^-$ storage rings PEPII, we reconstruct $B^-\to D^{*0} e^-\barν_e$ decays using the decay chain $D^{*0}\to{}D^0{}π^0$ and $D^{0}\to{}K^-π^+$. From the dependence of their differential rate on $w$, the product of the four-velocities of $B^-${} and $D^{*0}$, and using the description of the form factor $F(w)$ by Caprini et al., we obtain the preliminary results $ρ^2_{A_1} = 1.15\pm 0.06 \pm 0.08$, $F(1)\cdot|V_{cb}| = (36.3\pm 0.6 \pm 1.4)\cdot 10^{-3}$, and ${\cal B}(B^-\to D^{*0} e^-\barν_e) = (5.71\pm 0.08\pm 0.41)%$. The first errors are statistical and the second ones are systematic. \\ | |
