摘要：

The decays Y(4S) --> <B(B)over bar>, followed by B --> D*pi and D* --> D pi, permit reconstruction of all kinematic quantities that describe the sequence without reconstruction of the D, with reasonably low backgrounds. Using an integrated e(+)e(-) luminosity of 3.1 fb(-1) accumulated at the Y(4S) by the CLEO-II Il detector, we report measurements of B((B) over bar(0) --> D*(+)pi(-)) = (2.81 +/- 0.11 +/- 0.21 +/- 0.05) x 10(-3) and B(B- --> D*(0) pi(-)) = (4.34 +/- 0.33 +/- 0.34 +/- 0.18) x 10(-3).
