摘要：
A spin-dependent density-functional approach based on localized Hartree-Fock exchange potential is proposed for investigation of excited states and dynamics related to the excited states of atomic systems. In this approach, the electron spin orbitals in an electronic configuration are obtained by solving Kohn-Sham equation with an exact nonvariational spin-dependent localized Hartree-Fock exchange potential and the single-Slater-determinant energy of the electronic configuration is calculated by using these electron spin orbitals. This approach together with Slater’s diagonal sum rule has been applied to the calculation of multiplet energies of outer- and inner- shell excited states of atomic systems. This approach combined with linear response approximation has also been used to calculate the photoionization cross sections from the ground and excited states of atomic systems.
