is a parameter for AtomicState that specifies the total angularmomentum (electronic plus nuclear) quantum number for the state.


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

Details and Options

  • The value specified for F should be integer or half-integer.
  • F is automatically threaded over a list of AtomicState objects appearing as its argument.
  • If J and NuclearSpin are specified for state, values of F are automatically assigned to its sublevels returned by Sublevels[state].


Basic Examples  (2)

Define an atomic system, and generate its hyperfine and Zeeman sublevels using Sublevels.

Find the total angular momentum quantum number for each state.

If F is not defined, the value for J is returned instead.
