Simplified time-dependent Hartree-Fock calculations for atomic systems

Abstract

A simplified Time-Dependent Hartree-Fock scheme is discussed, involving the application of the method solely to the valence shell, and numerical results are presented for a number of atomic systems. An extensive study is made of the magnesium isoelectronic series and excellent agreement is observed between the TDHF oscillator strengths and the most accurate theoretical and experimental values. Results are also presented for the argon sequence.
