Briefly, if the emitted or observed photon has angular momentum k and parity [pi] = [(-1).sup.k] the transition is an electric multipole transition ([E.sup.k]), while the transition from absorbed photon with parity [pi] = [(-1).sup.k+1] is magnetic multipole transition ([M.sup.k]).
The intrinsic multipole transition moment and parity splitting were calculated.
