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, [0.126557575]), (0, 2, [0.300103593]), (0, 3, [0.056987912]), (2, 3, [0.114312578]), (2, 4, [0.0986363362]), (0, 5, [0.142498543])]

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.
