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.
