arc.alkali_atom_functions.printStateString# printStateString(n, l, j, s=None)[source]# Returns state spectroscopic label for numeric \(n\), \(l\), \(j\) label of the state. Optionally users can define \(s\), prompting printing \(2S+1\) index too (commonly used for Alkaline Earth atoms, while it is usually omitted for Alkali atoms) Parameters n (int) – principal quantum number l (int) – orbital angular momentum j (float) – total angular momentum s (float) – (optional) total spin momentum Returns label for the state in standard spectroscopic notation Return type string
