Atomic energy levels of zinc have been compiled for all stages of ionization for which experimental data are available. No data have yet been published for Zn IX, Zn X, Zn XXVI, and Zn XXVIII, and only several resonance lines of Zn XXIX and Zn XXX. Very accurate calculated values are compiled for Zn XXIX and Zn XXX. Experimental g‐factors and leading percentages from calculated eigenvectors are given. A value for the ionization energy, either experimental when available or theoretical, is included for the neutral atom and each ion. A review of the published literature is given. © 1995 American Institute of Physics and American Chemical Society.
