In recent years the aim of the electron-atom scattering experiments has been increasingly moving towards the so-called complete experiments from which the maximum information inherent to a given process can be deduced. The information derived from such an experiment usually takes the form of a complete set of scattering amplitudes and their relative phases - but it may, of course, be expressed by other equivalent parameter sets. Recent studies of orientation and alignment of states, excited by electron impact, are reviewed with an emphasis on experimental problems and development.

Anthraquinone derivatives are important anti-cancer drugs possessing, however, undesirable peroxidating and, in consequence, cardiotoxic properties. This results from the mediation by these compounds of the one-electron reduction processes of the oxygen molecule, which produces the highly toxic superoxide anion radical and other active oxygen species. This article summarizes the results of our studies on the molecular aspects of the mechanism of anthraquinone-mediated peroxidation which were carried out using enzymatic-assay, electrochemical, and quantum-mechanical methods.
