Interaction of Slow Electrons with High-Pressure Gases ('Quasi-Liquids'); Synthesis of Our Knowledge on Slow Electron-Molecule Interactions. Progress Report, June 1985-June 1986

摘要

A crucial step in efforts to develop not only a coherent picture of radiation interaction with matter, but also to understand radiation effects and mechanisms, as well as the effects of chemical pollutants and toxic compounds, is to relate the often abundant knowledge on isolated molecules (low pressure gases) to that on liquids or solids. To understand the roles of the physics and chemical properties of molecules in biological reactions, these ''isolated-molecule'' properties are related to molecules which are embedded in gradually thicker and thicker (denser and denser) gaseous and, finally, liquid environments. High pressure (40 to approx.8000 kPa) electron swarm experiments are currently in operation yielding information as to the effects of the density and nature of the environment on fundamental electron-molecule interaction processes at densities intermediate to those corresponding to low pressure gases and liquids, and the gradual transition from ''isolated molecule' to ''condensed phase'' behavior.
