Sr88_F3_Triplet_Robertson2021

class rydstate.species.strontium.sr88_vaillant2024_k_matrix_model_data.Sr88_F3_Triplet_Robertson2021(mqdt)

5snf 3F3 series, described by its Rydberg-Ritz quantum defects, since Vaillant 2024 has no triplet F models.

The singlet 5snf 1F3 series of the same symmetry is described by Sr88_F3_Singlet_Vaillant2024. Both series are treated as independent here, which is the same approximation as in the default Sr88 models (there, the 1F3 and 3F3 channels are the two uncoupled eigen channels of a single F J=3 model).

Parameters:

mqdt (MQDT)

species = 'Sr88'

The species for which the MQDT model is defined.

name = 'F J=3 triplet (Rydberg-Ritz), nu > 9'

The name of the atomic species.

f_tot = 3

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 = (9.0, inf)

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