An expression ior the transition matrix element between excited states is given in terms of the solutions to the time-dependent Ha-tree-Fock eigenvalue ditierendal equations. Some dipc4e oscillator saengths and transirioo moments are evaluated for members of the helium isoelectronic sequence.

โฆ Synopsis
The time dependent Hartree-Pock (TDHF) equations for ;i lithium atom in the continuum are simplified to yield an equation for the valence electron coupled to a pair of TDHF equations for the core. The analysis of Feshbach is applied to derive expressions for the locations, widths, and profile indices of the resonances arising from the Is* 'S + ~SJZF ' P excitations of the core; the expressions involve the TDHF core oscillator strengths. Results are presented for PI = 2, 3.4 and the reduced width at the series limit.

We advance a reformulation of the HartreeแFock problem in the context of the local-scaling transformation version of density functional theory. Explicit functionals of the energy are obtained. These functionals are expressed in terms of both the one-particle density and the local-scaling transformat
