Introduction,d fields, rely on a quantitative understanding of the electron and photon scattering processes for a variety of small molecules. The need for quantitatively accurate electron- and photon-molecule scattering cross sections is putting stringent demands on present theoretical methods. As this need beco

Application of the Close Coupling Method to Electron-Molecule Scattering,ry well known. The total wave function for an (N+1)-electron system consisting of an N-electron atom, ion, or molecule plus an additional electron is expanded in antisymmetrized products of N-electron target eignefunctions and a set of unknown functions representing the added electron. The unknown f

The application of discrete-basisset methods is further suggested by the success of these methods in molecular bound state calculations.

Polarization Potentials for Electron Scattering,ergy electron scattering (these energy ranges corresponds to roughly E >~ IP and IP >~ E >~ 10 IP, where E is the impact energy and IP is the target ionization potential). There are two approaches to the inclusion of such polarization effects in electron scattering. In the many-body approach, the sc

Vibrational Excitations of Low Energy e-CO Scattering,gy e-CO scattering. In this theory, the vibrational states of target molecules were coupled dynamically through the close-coupling approximation but with the direction of molecular axes fixed. The simultaneous vibrational and rotational transitions are then obtained from the adiabatic-nuclei approxi
