AtomicState

AtomicState[label]

represents a labeled atomic state.

AtomicState[label,par1val,par2val,…]

represents an atomic state with one or more specified atomic parameters

Details and Options

  • An atomic system is the first argument to many of the functions in the AtomicDensityMatrix package.
  • The label can be a number, string, or other expression. However, use of expressions other than numbers or strings as labels can reduce functionality when forming state selection criteria in functions like SelectStates.
  • The following atomic parameters can be specified:
  • Lelectronic orbital-angular-momentum quantum number
    Selectronic spin-angular-momentum quantum number
    Jtotal electronic angular-momentum quantum number
    NuclearSpinnuclear angular-momentum quantum number
    Ftotal angular-momentum quantum number
    M-projection of total angular momentum
    Parityparity; either Even or Odd
    Energyunperturbed energy (not including hyperfine shift in a hyperfine system)
    GFactor-factor
    NaturalWidthnatural linewidth
    Polarizability[rank]electric polarizability (scalar, vector or tensor)
    HyperfineAhyperfine coefficient
    HyperfineBhyperfine coefficient
    BranchingRatio[lab]branching ratio to level with label lab
  • A list of AtomicState objects is referred to as an atomic system.
