  "abstract": "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 the framework of HQET and calculate the O(1/m_Q) correction to the decay constants f_{-,1/2} and f_{+,3/2}. With the mass matrix of the two 1^+ states, we obtain the mixing angle for the two states and the interpolating currents, which couple to only one of the two eigenstates up to the order of 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 of O(1/m_Q) in HQET. The O(1/m_Q) correction to the decay amplitude of B_1 and B_2^* 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 sizeable for D system.",
