class rydstate.species.strontium.sr87_eigen_channel_model_data.Sr87_P45_LowN(mqdt)

Parameters:

mqdt (MQDT)

species = 'Sr87'

The species for which the MQDT model is defined.

name = 'P F=9/2 (clock), 1.8 < nu < 2.2'

The name of the atomic species.

f_tot = 4.5

Total angular momentum f_tot of the Rydberg state.

parity = -1

Parity (-1 or +1) of the Rydberg state, i.e. (-1)^(l_c + l_r) of its channels.

nu_range = (1.8, 2.2)

Range of effective principal quantum numbers nu for which the MQDT model is valid.

reference = 'NIST data of the 5s5p states'

Reference for the MQDT model, e.g., a publication doi where the model is described.

List of inner channels in the MQDT model.

outer_channels = [AngularKetFJ(i_c=4.5, s_c=0.5, l_c=0, s_r=0.5, l_r=1, j_c=0.5, f_c=4.0, j_r=0.5, f_tot=4.5, n_c=5), AngularKetFJ(i_c=4.5, s_c=0.5, l_c=0, s_r=0.5, l_r=1, j_c=0.5, f_c=4.0, j_r=1.5, f_tot=4.5, n_c=5), AngularKetFJ(i_c=4.5, s_c=0.5, l_c=0, s_r=0.5, l_r=1, j_c=0.5, f_c=5.0, j_r=0.5, f_tot=4.5, n_c=5), AngularKetFJ(i_c=4.5, s_c=0.5, l_c=0, s_r=0.5, l_r=1, j_c=0.5, f_c=5.0, j_r=1.5, f_tot=4.5, n_c=5)]

List of outer channels in the MQDT model.

eigen_quantum_defects = [[2.8720737, 0], [3.13689075, 0], [3.13143188, 0], [3.11955235, 0]]

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, 2, [1.31169947, -4.48280597])]

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.
