RESUME

ATOMIC ASTROPHYSICS AND SPECTROSCOPY
AND
BIOMEDICAL NANOSPECTROSCOPY
This homepage reports interdisciplinary research by the OSU group, with senior Research Scientist Sultana Nahar and several students, postdocs, and collaborators.

Research interests are theoretical studies of radiative and collisional atomic processes, and spectral formation in astrophysical and laboratory plasmas - an integrated program of atomic physics, astrophysics, and plasma physics.

This website will also report on the activties of a new cross-disciplinary program in biophysics: Computational Nanoscience and Biomedical Spectroscopy. Researchers include Sultana Nahar (Astronomy), Chris Orban (Physics), Russell Pitzer (Chemistry), Erica Bell (Radiation Oncology), Enam Chowdhury (Physics), Yan Yu (Thomas Jefferson University Medical School), Werner Eissner (University of Stuttgart), Max Montenegro (Universidad Catholica de Chile), Chiranjib Sur (IBM, India), and students Sara Lim (Biophysics Graduate Program), Ethan Palay, Michael Dance.

Recent developments entail theoretical and experimental studies to implement a new methodology, RESONANT NANO-PLASMA THERANOSTICS , based on the use of monochromatic X-ray sources for imaging, therapy and diagnostics (theranostics) in cancer research, as reported in the following news items.

The Opacity Project and the Iron/RmaX Project

The OSU group represents the U.S. participants in the international Opacity Project (OP) , and the Iron Project (IP/RmaX) Network aimed at large-scale atomic calculations using the relativistic R-matrix method for iron-peak elements and X-ray astrophysics. The databases TIPTOPBASE and OPSERVER offer OP and IP atomic data, and on-line calculation of "customized" astrophysical opacities, at the Ohio Supercomputer Center in Columbus Ohio.

This homepage is also intended as a guide to recommended ATOMIC DATA for astrophysical and laboratory applications. In addition, the database Nahar OSU Radiative Data (NORAD) contains a large number of datafiles for energy levels, transition probabilities, photoionization cross sections, and total and partial (electron+ion) recombination rate coefficients (including radiative and dielectronic recombination processes in a unified and ab initio manner using the R-matrix method).

The radiative data supercede earlier TOPbase data.
