Wavelengths, Transition Probabilities, and Energy Levels for the Spectra of Cesium (Cs  I–Cs  LV)

Energy level values, with designations and uncertainties, have been compiled for the spectra of the neutral atom and all positive ions of cesium (Z=55). Transition wavelengths with classifications, intensities, and transition probabilities are also tabulated. In addition, ground states, ionization energies, and hyperfine structure constants are listed. For most ionization stages experimental data are available; however, for those for which only theoretical calculations or fitted values exist, these are reported. There are a few ionization stages for which only a calculated ionization potential is available.
