Yb174_D2_LowN

class rydstate.species.ytterbium.yb174_eigen_channel_model_data.Yb174_D2_LowN(mqdt)

Parameters:

mqdt (MQDT)

species = 'Yb174'

The species for which the MQDT model is defined.

name = 'D J=2, 2 < nu < 5'

The name of the atomic species.

f_tot = 2

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 = (2.0, 5.0)

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

reference = 'fit to NIST data between 5d and 7d'

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

inner_channels = [AngularKetLS(i_c=0.0, s_c=0.5, l_c=0, s_r=0.5, l_r=2, s_tot=0.0, l_tot=2, j_tot=2.0, f_tot=2.0, n_c=6), AngularKetLS(i_c=0.0, s_c=0.5, l_c=0, s_r=0.5, l_r=2, s_tot=1.0, l_tot=2, j_tot=2.0, f_tot=2.0, n_c=6)]

List of inner channels in the MQDT model.

outer_channels = [AngularKetFJ(i_c=0.0, s_c=0.5, l_c=0, s_r=0.5, l_r=2, j_c=0.5, f_c=0.5, j_r=2.5, f_tot=2.0, n_c=6), AngularKetFJ(i_c=0.0, s_c=0.5, l_c=0, s_r=0.5, l_r=2, j_c=0.5, f_c=0.5, j_r=1.5, f_tot=2.0, n_c=6)]

List of outer channels in the MQDT model.

eigen_quantum_defects = [[2.703156, 0.973192], [2.724546, 0.372621]]

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, [-0.948409, -2.12127])]

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.
