HyperfineA

HyperfineA
is a parameter for AtomicState that parameterizes the hyperfine splitting of the state due to the electronic interaction with the nuclear magnetic dipole moment.
HyperfineA[state]
returns the value specified for HyperfineA in AtomicState state, or HyperfineA[StateLabel[state]] if it is not specified.
  • HyperfineA is considered to have units of angular frequency.
  • The hyperfine shift of a state with HyperfineA and HyperfineB denoted by A and B, respectively, is given by , where K=F(F+1)-J(J+1)-I(I+1) and F, I, and J are the total, total electronic, and total nuclear angular-momentum quantum numbers, respectively.
  • HyperfineA is automatically threaded over a list of AtomicState objects appearing as its argument.
