Figure 1 is a periodic table of the elements showing data of interest to x-ray crystallographers and spectroscopists. No guarantee is made concerning accuracy of the data, since data were gathered from many publications, both new and old. It is recognized that many constants are missing on the chart. Where widely conflicting data were found, no entry was made in the table. Note that atomic weight is based on carbon twelve, all wavelengths are in angstrom units, and excitation potentials are in kv. Submitted May 18, 1962
