Atomic and molecular physics (AMP)
Dr.
A. Z. Msezane's research includes electron/photon interactions with atoms/ions.
Regge pole trajectories for singular and nonsingular potentials are of
particular interest in the context of heavy particle collisions. Correlations
and nondipole effects are investigated through the generalized oscillator
strength.
Dr.
Zhifan Chen's research is
directed toward understanding of the fundamental details of the
inner-shell electron dynamics of an open-shell atoms or ions through
theoretical analysis of the interaction between photon, electron and atoms.
Specific topics of recent studies include: (1) Deriving the equations to perform
the calculation of the 'forward' and 'backward' Coulomb matrix elements for the
inner-shell electron transition. (2) Developing the method of random
phase approximation with exchange involving the inner-shell process of an
open-shell atom. (3) Calculating the cross sections
of the photoionization, angular distribution of the photon electron, and the
oscillator strength for the open-shell atom and the atoms in the excited states
with particular interest to the important correlation and polarization
effects.
Dr. Zineb Felfli's researchs focus on the following areas: The many-body problem
in Nuclear Physics and in particular, the three-body problem using the
hyperspherical harmonics approach. Collision problem in Atomic Physics,
with special emphasis on the photoionization of open-shell and highly ionized
systems of relevance to Astrophysics, Fusion and Laboratory Plasmas. Development
of theoretical approaches based on the Regge Pole Theory that allow for an
efficient investigation of potential scattering problems. Future projects
include the analysis of data from various space missions as well as an extension
of the present research to molecular systems.
