The hyperfine effects emerging in all spectra of atomic Rydberg states are due to the nuclear effects including hyperfine structure and isotope shifts. The autoionizing Rydberg states converging to 6p〓 and 4f〓 5d6s 〓 [3/2] 〓 limits were investigated by three photon excitation. In the study of the spectra for those converging to 6p〓 limit, the ICE (Isolated-core excitation) model has been proved to be suitable for describing the excitation of the autoionizing Rydberg states with a lowly excited core.
