By the use of one or other of the available methods, the data for
neutral atoms are complete as far as atomic number 38, with the
exception of carbon (6), fluorine (9) and germanium (32). The data
for ionized atoms are also increasing, at the present time, in a
very gratifying manner. The “hot spark” investigations of Millikan
and Bowen,[14] which permit the estimation of the fifth and sixth
ionization potentials of certain light atoms, are not included in
the table. Under the conditions hitherto investigated in the stellar
atmosphere, ionization corresponding to a potential of about fifty
volts is the highest encountered, and accordingly ionization potentials
that greatly exceed this value have no place in the present tabulation
of astrophysically useful data. A knowledge of the higher critical
potentials[15] is, however, of great interest in connection with the
theoretical problems of the far interior of the star.
