Energy relationships and ionization potentials of atoms of the first row of the periodic table in all stages of ionization

摘要

With the aid of the four agencies listed below we have been able to complete the identification of all of the extreme ultra-violet lines (λ = 2000 A to λ = 200 A) of any strength emitted by the atoms of the first row of the periodic table in all stages of stripping. The main features of the spectra of these atoms may then be considered as now determined. The agencies used in these identifications are the following.
