The energy levels and observed spectral lines of the krypton atom, in all stages of ionization for which experimental data are available, have been compiled. Sufficient data were found to generate level and line tables for Kr I through Kr X and Kr XVIII through Kr XXXVI. For Kr XXXV and Kr XXXVI and most of Kr XXXIV theoretical values are compiled for the energy levels. In all of the other stages a few lines, some of which may be only tentative classifications, are reported. In addition for Kr I, separate tables of energy levels are tabulated for the isotopes 86Kr and 84Kr. Experimental g-factors are included for Kr I and Kr II. A value, either experimental, semi-empirical, or theoretical, is included for the ionization energy of each ion.
