qspec.simulate.gen_electronic_state  (  freq_j = 0.0 ,  parity = None ,  j = 0 ,  i = 0 ,  ls = None ,  jj = None ,  hyper_const = None ,  gj = None ,  gi = 0 ,  label = None  )[source]

Creates all substates of a fine-structure state $|\mathrm{[label]}\pi JI\rangle$ using a common label.

Parameters:

freq_jquant_like

The energetic position of the state without the hyperfine structure or the magnetic field (MHz).

paritybool | str

The parity $\pi$ of the state is used to check the selection rules. If None, it is inferred from ls if possible. It can be either 'even' ('e', False) or 'odd' ('o', True).

jquant_like

The electronic total angular momentum quantum number $J$.

iquant_like

The nuclear spin quantum number $I$.

lsquant_like | Iterable

A list or a single pair of electronic angular momentum and spin quantum numbers $(l_i, s_i)$ used to check the selection rules and to calculate the electronic g-factor in the LS-coupling scheme. If this is a list of LS-pairs, the parameter jj requires a list of $j_i$ quantum numbers.

jjquant_like | Iterable

A list of two electronic total angular momentum quantum numbers $(j_0, j_1)$ used to calculate the electronic g-factor in the jj-coupling scheme. Either a list of two $(l_i, s_i)$ pairs needs to be specified for the parameter ls or a list of g-factors $g_{j_i}$ for the parameter gj.

hyper_constIterable[array_like]

A list of the hyperfine-structure constants. Currently, constants up to the electric quadrupole order are supported ($A$, $B$). If 'hyper_const' is a scalar, it is assumed to be the constant $A$ and the other orders are 0 (MHz).

gjarray_like

A list of two $g_{j_i}$ or a single electronic g-factor $g_J$. If gj is a list, jj is required and ls is overwritten. If gj is a scalar, both ls and jj are overwritten.

giarray_like

The nuclear g-factor $g_I$.

labelstr

The label of the states. The labels are used to link states via a DecayMap.

Returns:

stateslist[qspec.simulate.State]

A list of the created states $|\mathrm{[label]}\pi JIFm\rangle$.
