LevelPlot.makeLevels(nFrom, nTo, lFrom, lTo, sList=[0.5])[source]#

Constructs energy level diagram in a given range

Parameters

  • nFrom (int) – minimal principal quantum number of the states we are interested in

  • nTo (int) – maximal principal quantum number of the states we are interested in

  • lFrom (int) – minimal orbital angular momentum of the states we are interested in

  • lTo (int) – maximal orbital angular momentum of the states we are interested in

  • sList (float) – optional, spin angular momentum. Default value of [0.5] corresponds to Alkali atoms. For Alkaline Earth it has to be specified. For divalent atoms one can plot either one spin state by setting for example sList=[0]`, or both spin states sList=[0,1]`
