But as the spectra of highly ionized atoms have been studied in the laboratory, these values have been determined more precisely, and we have striven to incorporate them in the American edition of the book.

These tables were prepared under the auspices of the Committee on Line
Spectra of the Elements of the National Academy of Sciences — National
Research Council. They contain the outstanding spectral lines of neutral (I),
singly ionized (II), doubly ionized (III), triply ionized (IV), and quadruply ionized (V
), atoms. Listed are lines that appear in emission from the vacuum ultraviolet to
the far infrared. For most atoms these lines were selected from much larger lists
in such a way as to ...

In other words, emission line intensities in residual arc spectra (barring self-
absorption) are proportional to the number of radiating atoms; and relative
intensities may therefore be derived from concentrations at which different lines
show the same ... Furthermore, it is known [18] that the second ionization
potential of these elements ranges from 10 to 75 v and that the strongest lines of
singly ionized atoms generally have shorter wavelengths than those of neutral
atoms, nearly half of ...

It was, of course, the study of these spectral lines that originally led to the

justified for neutral atoms and for simpler atomic systems with only a few

justified for highly ionized ...

strong ion lines and by weak neutral lines and weak or absent bands; the very
