T1 - On the systematic linear variation of atomic expectation values
AU - Cohen, M.
PY - 1979
Y1 - 1979
N2 - The systematic variation of both exact and Hartree-Fock expectation values as asymptotically linear functions of the nuclear charge Z is derived, and the unusually high accuracy of certain Hartree-Fock values explained, by means of Z-dependent perturbation theory, the Hellmann-Feynman theorem and the virial theorem.
