The R-matrix method is an embedding procedure which is based on the division of space
into an inner region where the physics is complicated and an outer region for which greatly …

The current state of the theory and its application to low-energy electron-molecule collisions
is reviewed. The emphasis is on elastic scattering and vibrational and rotational excitation of …

Electron-Molecule Interactions and Their Applications, Volume 2 provides a balanced and
comprehensive account of electron-molecule interactions in dilute and dense gases and …

Publisher Summary This chapter discusses the R-matrix concept of atomic processes. The R-
matrix method was first introduced by Wigner and Eisenbud with a fundamental idea that …

A new method of implementing scattering calculations is presented. For the S-matrix
computation it produces a complete set of solutions of the wave equation that need be valid …

The R-matrix propagation method for solving the close coupled equations for inelastic
scattering is presented. The method is shown to be fast, accurate, and stable without the …

The R-matrix method for electron scattering by diatomic molecules, developed in the
authors' earlier papers, is extended to describe vibrational excitation and dissociative …

A theoretical coupled-channels investigation of eC O 2 scattering is reported for incident
electron energies from 0.07 to 10.0 eV. The fixed-nuclei approximation is made with the …

Calculations of cross sections for elastic eN 2 collisions have been performed for impact
energies from 0.01 to 1.0 Ry using model exchange potentials based on a free-electron-gas …

In continuation of Paper I of this work we describe a practical application of the combination
of complex absorbing potentials (CAPs) with Green's functions. We use a new approach for …
