Abstract
We have studied semileptonic B meson decays with a p-wave charm meson in the final state using 3.29 x 10(6) B (B) over bar events collected with the CLEO II detector at the Cornell Electron-Positron Storage Rin g. We find a value for the exclusive semileptonic product branching fr action B(B- --> D(1)(0)l(-) <(nu)over bar>(l))B(D-1(0)-->D(+)pi(-) )= (0.373 +/- 0.085 +/- 0.052 +/- 0.024)% and an upper limit for B(B- -- > D(2)(0)l(-)<(nu)over bar>)(l))B(D2O --> D*+ pi(-)) < 0.16% (90% C.L .). Furthermore, we present the first measurement of the q(2) spectrum for B- --> D(1)(0)l(-)<(nu)over bar>(l).
