【 摘 要 】

Electron-molecule and electron-atom collisions initiate and drive almost all the relevant chemical processes associated with radiation chemistry, environmental chemistry, stability of waste repositories, plasma-enhanced chemical vapor deposition (CVD), plasma processing of materials for microelectronic devices and other applications, and novel light sources for research purposes (e.g. excimer lamps in the extreme ultraviolet) and in everyday lighting applications. The life sciences are a rapidly advancing field where the important role of electron-driven processes is only now beginning to be recognized. It has been shown very recently that low-energy electrons with energies significantly below the ionization energies of DNA molecules can initiate single and double strand-breaking in DNA molecules. Sanche and co- workers identified some of the key mechanisms involved as electron attachment processes. Electrons also drive many of the key processes in chemical synthesis, in planetary atmospheres, and in low-pressure and high-pressure plasmas used in environmental remediation applications.
