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- -> D*0 e- nubar decays using the decay chain
D*0 -> 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 D*0,
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- -> D*0 e- nubar) = (5.56 +- 0.08 +- 0.41)%.
