NIST 38. NIST Spectroscopic Properties of Atoms and Atomic Ions Database
J R. Rumble
The NIST Spectroscopic Properties of Atoms and Atomic Ions Database provides listings of prominent air or vacuum emission wavelengths for neutral atoms and their first four stages of ionization. Supplementary data included in the database are: atomic mass; ground-state term and configuration; and ionization potentials for theneutral atom and first four stages of ionization. For all stable isotopes, the following are given: atomic weights; abundances; nuclear spin; and dipole and quadrupole moments.
