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

Contribution of the Variable Phase Method to the Frame Transformation Theory of Rotational Excitati techniques — a close coupling (CC) type one-center expansion with . of the molecule, and . to describe the motion of the colliding electron in the laboratory frame (LF) anisotropic molecular field- becomes a prohibitive task as soon as one wants to go beyond the rotational excitation of the lighter

The T-Matrix Method in Electron-Molecule Scattering,ical methods, has lead to renewed interest in discrete-basis-set methods. The application of discrete-basisset methods is further suggested by the success of these methods in molecular bound state calculations. Although the standard albegraic variational methods of Hulthen,. Kohn,. and Rubinow. have

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
