List of eigen quantum defects for the close-coupling channels. Each entry is a list of polynomial coefficients; a constant is a single element list.

mixing_angles = [(0, 1, [0.21157531, -15.3844]), (0, 2, [0.00521559431]), (0, 3, [0.0398131577]), (1, 3, [-0.0071658109]), (0, 4, [0.10481227]), (1, 4, [0.0721660042])]

List of mixing angles between close-coupling channels. Each entry is a tuple (i_idx, j_idx, coefficients) where i_idx and j_idx are the indices of the involved channels and coefficients is the list of expansion coefficients for the energy dependence of the angle (a constant angle is a single element list). The energy dependence is expanded in the nui of the first channel of the model, see calc_frame_transformation_inner_closecoupling(). The default None means no mixing between the close-coupling channels.
