We present measurements of the branching fractions for the three-body decays
B0 -> D(*)-/+ K0 pi^+/-$ and their resonant submodes $B0 -> D(*)-/+ K*+/- using a sample of
approximately 88 million BBbar pairs collected by the
BABAR detector at the PEP-II asymmetric energy storage ring.
%
We measure:
B(B0->D-/+ K0 pi+/-)=(4.9 +/- 0.7(stat) +/- 0.5 (syst)) 10^{-4}
B(B0->D*-/+ K0 pi+/-)=(3.0 +/- 0.7(stat) +/- 0.3 (syst)) 10^{-4}
B(B0->D-/+ K*+/-)=(4.6 +/- 0.6(stat) +/- 0.5 (syst)) 10^{-4}
B(B0->D*-/+ K*+/-)=(3.2 +/- 0.6(stat) +/- 0.3 (syst)) 10^{-4}
%
From these measurements we determine the fractions of resonant events
to be
f(B0-> D-/+ K*+/-) = 0.63 +/- 0.08(stat) +/- 0.04(syst)
f(B0-> D*-/+ K*+/-) = 0.72 +/- 0.14(stat) +/- 0.05(syst)
