PDF Version Also Available for Download.

Description

The project was undertaken in collaboration with Dr. Neal Snyderman of Lawrence Livermore National Laboratory (LLNL) through a project under the directorship of Dr. Kennedy Reed of LLNL. It is a collaboration of the work started at LLNL during the summers of 1994 and 1995, and continued at Spelman College. Spelman students Adrienne Stiff and Joy Harris were supported under this project. The main question under investigation was whether a Sturmian representation of the electron Green function is suitable for numerical calculations of QED effects in high-Z helium-like atoms. The frequency-independent part of the two-photon exchange graphs was calculated with ... continued below

Description

The project was undertaken in collaboration with Dr. Neal Snyderman of Lawrence Livermore National Laboratory (LLNL) through a project under the directorship of Dr. Kennedy Reed of LLNL. It is a collaboration of the work started at LLNL during the summers of 1994 and 1995, and continued at Spelman College. Spelman students Adrienne Stiff and Joy Harris were supported under this project. The main question under investigation was whether a Sturmian representation of the electron Green function is suitable for numerical calculations of QED effects in high-Z helium-like atoms. The frequency-independent part of the two-photon exchange graphs was calculated with this representation and compared with the results of other recent calculations. Only the Coulomb part of these graphs were calculated under this project.
