  author={William Clyde Martin and Lucy Hagan and Joseph Reader and Jack Sugar},
  journal={Journal of Physical and Chemical Reference Data},
Values of the first four ionization potentials of the lanthanides (Z=57–71) and of Hf have been compiled. All except the value for neutral Hf are based on spectroscopic data. The spectroscopic designations of the ground levels of the neutral through triply ionized atoms (Z=57–72) are also tabulated. A similar compilation for the actinides (Z=89–103) lists Sugar's recent values for the first ionization potentials through No (Z=102). Accurate spectroscopic ionization potentials have been… Expand
