F

F
is a parameter for AtomicState that specifies the total angular-momentum (electronic plus nuclear) quantum number for the state.
F[state]
returns the value specified for F in AtomicState state, or J[state] if it is not specified.
  • 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].
Define an atomic system, and generate its hyperfine and Zeeman sublevels using Sublevels.
