Abstract:

Three major sets of computer programs have been extensively modified and extended. These programs are a molecular code for finite clusters of atoms with the coding optimized for clusters with cubic point group symmetry, a thin film code for several interacting infinite two-dimensional sheets of atoms, and a crystal code for an infinite number of atoms with cubic symmetry. These programs provide a predictive capability for clusters and platelets of atoms, surfaces and perfect crystals through first-principles calculations at the Unrestricted Hartree-Fock level. These programs have been provided to and used by several USAF personnel. Author
