Energy Levels and Observed Spectral Lines of Neutral and Singly Ionized Chromium, Cr I and Cr II



Edward B. Saloman


The energy levels and observed spectral lines of neutral and singly ionized chromium atoms have been compiled. Tables of energy levels and spectral lines are generated for each stage. Experimental g-factors and leading percentages are included when available. An experimental value for the ionization energy for each stage is provided.
