The effect of electron correlation on atomic properties

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+, KL1L1 Auger energies in C and O, lifetimes in the Si 3s3p3 3D° → 3s23p2 3P isoelectronic sequence, and the hyperfine structure of Be and B 1s22p2P° states, which not only are of interest in themselves but illustrate points (a) and (b) above.
