β¦ Synopsis
A kinetic energy analysis of total energy differences in 115 atomic multiplet states is presented. We show by numerical restricted Hartree-Fock calculations that there is a reasonably accurate linear relationship between the kinetic energy of the electrons in open subshells and the total energy within a manifold of states arising from the same sp" or s 2 p n ( n = 2,3,4) electron configuration in main-group atoms.

Using several types of simple generating orbitals, explicit expressions for w x w x the kinetic-energy functional T and the exchange functional E were generated in the context of the local-scaling transformation version of density functional theory. The variational parameters in these orbitals were
