class rydstate.species.ytterbium.yb174_mqdt_fmodel_data.Yb174_S1_LowN(mqdt)

Parameters:

mqdt (MQDT)

species: ClassVar[str] = 'Yb174'

The species for which the MQDT model is defined.

name: ClassVar[str] = 'S J=1, 2 < nu < 26'

The name of the atomic species.

f_tot: ClassVar[float] = 1

Total angular momentum f_tot of the Rydberg state.

nu_range: ClassVar[tuple[float, float]] = (2.0, 26.0)

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

reference: ClassVar[str | tuple[str, ...] | None] = 'fit to NIST data between 7s and 13s, extrapolation seems good up to 30s'

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

inner_channels: ClassVar[list[AngularKetBase[Any]]] = [AngularKetLS(i_c=0.0, s_c=0.5, l_c=0, s_r=0.5, l_r=0, s_tot=1.0, l_tot=0, j_tot=1.0, f_tot=1.0)]

List of inner channels in the MQDT model.

outer_channels: ClassVar[list[AngularKetFJ[Any]]] = [AngularKetFJ(i_c=0.0, s_c=0.5, l_c=0, s_r=0.5, l_r=0, j_c=0.5, f_c=0.5, j_r=0.5, f_tot=1.0)]

List of outer channels in the MQDT model.

eigen_quantum_defects: ClassVar[list[tuple[float, ...] | list[float] | float]] = [[0.432841, 0.724559, -1.95424]]

List of eigen quantum defects for the close-coupling channels. Each entry can be a constant or a list of polynomial coefficients.

mixing_angles: ClassVar[list[tuple[int, int, tuple[float, ...] | list[float] | float]]] = []

List of mixing angles between close-coupling channels. Each entry is a tuple (i_idx, j_idx, params) where i_idx and j_idx are the indices of the involved channels and params are the parameters for the energy dependence of the angle (constant or polynomial coefficients).
