Research Interests
I have been interested in the application of the nuclear charge expansion
theory to the calculation of atomic energy levels and oscillator strengths by
using perturbation theory and the calculation of fine structure splittings and
transition probabilities of forbidden transitions in highly ionized atoms using
multi-configuration Dirac-Fock method. My recent research efforts are mainly in
the area of application of the Binary-Encounter-Bethe model of Kim and Rudd to
calculate ionization cross sections of atoms and molecules by electron impact
which are needed for technological applications and modeling of plasma
processing for fabrication of semiconductor materials.
