The study of polarization of atomic radiation emitted after impact excitation has yielded an
enormous wealth of detailed information on the mechanism and dynamics of collisional …

This book provides a comprehensive and up-to-date account of the field of low energy
positrons and positronium within atomic and molecular physics. It begins with an …

This article reviews a particular area of perturbation theory in which there has been much
activity during the past ten years. This area embraces distorted-wave Born series, the …

Distorted-wave methods in the theory of electron-impact exitation of atoms and atomic ions
are reviewed. Principal methods of derivation of the distorted wave approximation are …

New experimental electron-energy-loss data have been used to extract differential and
integral cross sections for excitation of the 2 1 P level, and for the overlapping (3 1 P, 3 1 D …

Integral and differential cross sections and electron-impact coherence parameters have
been calculated for the 6 s 2 p 1 P 1 transition in neutral barium using both the distorted …

The electron-photon coincidence technique has been employed in experimental
investigations aimed at elucidating the finer details of the excitation of the first excited states …

We have calculated differential cross sections as a function of the projectile scattering angle
for positron-helium and positron-krypton collisions using the classical-trajectory Monte Carlo …

Recent developments in the field of alignment and orientation studies of electron impact
excitation of atoms are discussed. The article reviews experiments which have a well …
