Welcome to my homepage!
Research [Radiative (
NORADAtomic-Data) & Collisional Atomic Data links are given down below]:
1. Radiative and collisional atomic processes in laboratory and
astrophysical plasmas:
(click a topic for brief outline)
Photoionization
Electron-ion recombination
Radiative transition probabilities
Electron-ion scattering
2. Theoretical Spectroscopy
3.
Computational Nanospectroscopy for Biomedical Applications
4. Development of theories and programs for state-of-the art methods for
atomic parameters, currently dielectronic
satellite lines in astrophysical plasmas
5. A member of the international collaborations,
the Opacity
Project and
the Iron Project , to calculate accurate atomic parameters for
astrophysically abundant atoms and ions
These atomic processes are dominant in astrophysical plasmas. The
results are applicable to both astrophysical and laboratory plasmas for
spectral and diagnostic analysis.
Theoretical calculations employ state-of-the-art quantum mechanical
techniques based on the ab initio R-matrix method in the close coupling
approximation.
A significant part of the research is under the two international
projects, the Opacity Project and the Iron Project, for calculating
accurate atomic parameters for astrophysically abundant atoms and ions,
and the interdisciplinary program on nanoscience.
Applications:
Fe I - Fe III in 1Zwicky1
