The structure of free algebras,The basic concept of density matrices is introduced. It is demonstrated how reduced density matrices relate theoretical scattering amplitudes to experimental observables. A computer program is presented to calculate various observables from bilinear products of scattering amplitudes for impact excitation of (quasi) one-electron atoms.

Electron-Atom Scattering Theory: An Overview,A summary of the basic equations that are used in the electron-atom collision calculations discussed in this book is presented. We begin with the simplest case of potential scattering, before we introduce integral equation approaches for the transition operator and, finally, the close-coupling expansion.

Core Potentials for Quasi One-Electron Systems, approximate inclusion of exchange effects between the valence electrons and the core removes the unphysical structure in the potential function that is characteristic for potentials calculated by only including the effect of core polarization due to the valence electrons.

The Close-Coupling Approximation,s. A computer program, based upon an integral-equation approach combined with an asymptotic correction procedure, is presented together with some sample input and output data for positron scattering from lithium atoms.
