Measurement of the Decay B- --> D*0 e- nubar

Using 226 million BBbar events recorded on the Upsilon(4S) resonance with the BABAR detector at the SLAC e+e- PEPII storage rings, we reconstruct B- -> D0 e- nubar decays using the decay chain D0 -> D0 pi0 and D0 -> K pi. From the dependence of their differential rate on w, the dot product of the four-velocities of B and D0, and using the form factor description by Caprini et al. with the parameters F(1) and rho_A1^2, we obtain the results rho_A1^2 = 1.16 ± 0.06 ± 0.08, F(1)|V_cb| = (35.9 ± 0.6 ± 1.4) 10^-3, and BF(B- -> D0 e- nubar) = (5.56 ± 0.08 ± 0.41)%.
