solrat.atom_model.multi_term_atom_model.data.MnI.get_Mn_I_5432_config() → MultiTermAtomConfig[source]¶

Atomic model for Mn I 5432.5 A line, constrained to \(J=5/2 \to J=5/2\) transition.

Note that Mn I 5432.5 A transition is \(S=3.5 \to S=2.5\), i.e. it is forbidden under strict \(LS\) coupling. Here it is modeled by expanding the upper term into two terms of different multiplicities.

Note that Mn I 5432.5 A line also has significant HFS, which, however, can be modeled by artificially increasing the turbulent velocity (provided that the line width is large enough to begin with).

Returns:: MultiTermAtomConfig instance

Due to rather crude approximations applied, this atomic model is recommended to be used with LTE SEE only.
