Developments in the semiclassical close-coupling description of atomic collisions, in an
energy range of roughly 0.1 up to a few hundred keV per nucleon of the projectile, are …

1" 1. Foreword.-First experiments on electron interaction with gases started soon after the
discovery of this elementary particle. One hundred years ago, Lenard (1894, 1895, 1903) …

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 …

A pulsed crossed-beam technique incorporating time-of-flight spectroscopy which was
recently developed in this laboratory has been applied to measurements of the cross …

Atomic Multielectron Processes is the first comprehensive collection of the data (mostly cross
sections and methods) devoted to the multielectron transitions in atoms and ions induced by …

Publisher Summary The chapter focuses on the multielectron transitions in high-velocity
atomic transitions—that is, multiple ionization, electron transfer, excitation, and …

Data and analysis for the ratio of double to single ionization in helium is reviewed for impact
by photons and charged particles. In the case of photoionization there are two processes …

Measurements of the cross sections for single and double ionization of helium as well as for
the creation of H 2+ and H+ ions from H 2 for impact of antiprotons in the energy range 13 …

The single-ionization cross sections sigma+ for positron impact on H 2, He, Ne and Ar have
been measured from the ionization threshold to the high-energy region where the positron …

Angular correlations between the three outgoing electrons in the double ionization of argon
by electron impact have been measured for the first time. Double and triple coincidence …
