MQDTStrontium87

class rydstate.species.strontium.MQDTStrontium87[source]

MQDT models for Sr87 of F. Robicheaux in the eigenchannel formulation.

See sr87_eigen_channel_model_data for the models and references. Apart from the Robicheaux 2019 models, it contains a model for the 5s5p states based on NIST data.

Parameters:

  • args (object)

  • kwargs (object)

Return type:

CachedT

species: ClassVar[str] = 'Sr87'

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=4.5, s_c=0.5, l_c=0, j_c=0.5, f_c=4.0, n_c=5): (45932.287373577, '1/cm'), CoreKet(i_c=4.5, s_c=0.5, l_c=0, j_c=0.5, f_c=5.0, n_c=5): (45932.120512528, '1/cm')}

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

reference_ionization_threshold_tuple: ClassVar[tuple[float, str] | None] = (45932.1956, '1/cm')

The reference ionization threshold, which is used to define the zero of energy for the MQDT models. If None, it is defined as the smallest ionization threshold in the ionization_threshold_dict.

model_classes: ClassVar[list[type[MQDTModel]]]

List of the MQDT MQDTModel models available for this species.
