The object of this paper is threefold, (a) to establish how nonrelativistic correlation theories may be applied to any atom of the periodic table; (b) to formulate a procedure based on a definition of the “Fermi sea” for predicting the importance of correlation effects on atomic properties other than total energies; and (c) to present new results on Is binding energies in C, F, F − , Ne, Na, and Na + , KL 1 L 1 Auger energies in C and O, lifetimes in the Si 3 s 3 p 3 3 D° → 3 s 2 3 p 2 3 P isoelectronic sequence, and the hyperfine structure of Be and B 1 s 2 2 p 2 P ° states, which not only are of interest in themselves but illustrate points (a) and (b) above.
