Energy Levels and Observed Spectral Lines of Krypton, Kr I through Kr XXXVI

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–Kr X and Kr XVIII–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 Kr86 and Kr84. Experimental g factors are included for Kr I and Kr II. A value, either experimental, semiempirical, or theoretical, is included for the ionization energy of each ion.
