摘要	We first improve the previous results on the masses of the doublets (0(+),1(+)) and ( 1(+),2(+)) with QCD sum rules up to the order of O(1/m(Q)) in HQET. With the mass matrix of the two 1 (+) slates, we obtain the mixing angle for the two states and construct the interpolating currents which couple to only one of the two eigenstates up to the order O(1/m(Q)). Using these results we derive the light-cone sum rules for the amplitudes of the pionic decay of B-1 and B-2* up to the order O(1/m(Q)) in HQET. The O(1/m(Q)) terms in these amplitudes are found to be small. When applied to D-1 and D-2* the theoretical results are in good agreement with experimental data though the theoretical uncertainty is sizable for the D system. [S0556-2821(98)02319-3]
