Energy Level and Line Tables for One-Electron Atomic Spectra*

Abstract

Tables are presented showing precise values of the energy levels and lines of the spectra 1H i to 40Ca xx according to an equation expected to exhibit a relative uncertainty of the order of 10−11Z7. Only one isotope per element is listed beyond Li iii. All levels are given up to n values ranging from 12 for H i to 4 for Ca xx and those of lowest and highest j up to n values ranging from 50 for H i to 8 for Ca xx. For each line complex with given n and n′, the wavenumbers of the two extreme lines and the statistical mean are given up to values ranging from n = 20, n′ = 12 f or 1H i to n = 7, n′ = 6 for 40Ca xx.
