MQDTStrontium88

class rydstate.species.strontium.MQDTStrontium88

MQDT models for Sr88 of F. Robicheaux in the eigenchannel formulation.

See sr88_eigen_channel_model_data for the models and references. Apart from the Robicheaux 2019 models, it contains a model for the 5s5p 1P1 and 3P1 states fitted to NIST data. The Robicheaux models only contain the 5snl channels and are valid for high effective principal quantum numbers, see MQDTStrontium88Vaillant2024 for models including the doubly excited perturber channels.

Parameters:

• args (object)

• kwargs (object)

Return type:

CachedT

species: ClassVar[str] = 'Sr88'

The short name of the atomic species.

tag: ClassVar[str | None] = 'robicheaux2019'

The tag for these MQDT parameters.

is_default: ClassVar[bool] = True

Whether this MQDT is the default MQDT for the species.

ionization_threshold_dict: ClassVar = {CoreKet(i_c=0.0, s_c=0.5, l_c=0, j_c=0.5, f_c=0.5, n_c=5): (1377012721, 'MHz')}

Dictionary containing the ionization thresholds for the different core states. The thresholds are given in the form of a tuple (ionization_threshold, unit).
