Theory of Optical Absorption with Electron-Hole Attraction

November 1, 1998
Author(s)
Eric L. Shirley, L Benedict, Robert B. Bohn
This work presents calculations of the optical absorption spectra of semiconductors and insulators. The background and underlying physics are discussed, and the efficient computational method used is sketched. Results for eight solids are presented and

Revised Formulas for Diffraction Effects With Point and Extended Sources

October 1, 1998
Author(s)
Eric L. Shirley
Revised formulas to estimated diffraction effects in radiometry for point and extended sources are derived. They are found to work as well as or better than previous formulas. In some instances the formulas can be written in closed form; otherwise, their

Local-density-functional calculations of the Energy of Atoms

January 1, 1997
Author(s)
Svetlana A. Kotochigova, Zachary H. Levine, Eric L. Shirley, Mark D. Stiles, Charles W. Clark
The total energies of atoms and with atomic number Ζ from 1 to 92 and singly-charge cations with Ζ from 2 to 92 have been calculated to an accuracy of 1 υHartree within four variants of the Kohn-Sham local-density approximation. The approximations
