is a parameter for AtomicState that specifies the electronic orbital angularmomentum quantum number for the state.


returns the value specified for L in AtomicState state, or L[StateLabel[state]] if it is not specified.

Details and Options

  • L should be set to integer values.
  • L is used to determine the -factor for an atomic state. If the parameter GFactor is specified, or the -factor is not required, then the value of L is not used.
  • L is automatically threaded over a list of AtomicState objects appearing as its argument.

Two-level atomic system with Zeeman structure.

The values of L, S, and J are used to find the Landé -factor for each state.

The -factor enters in the magnetic-field interaction Hamiltonian.
