Many everyday phenomena are related to interactions of photons, electrons and electromagnetic waves with matter. Some have been fascinating people for centuries: northen lights, sunrise and sunset, night sky full of stars etc. There are also many new devices and phenomena, some of which we take for granted: the screen of our computer or television set, or the bar code reader in grocery store. Many of these devices would not exist,where it not for the work of many scientists who were solving problems in plasma physics, that many people would consider unimportant at the time. Our research, which will produce many electron impact cross sections, will help to better understand processes in low temperature plasmas which are important for the semiconductor industry or for various processes taking place in the stratosphere.

许多日常现象都与光子、电子和电磁波与物质的相互作用有关。几个世纪以来，有些东西一直吸引着人们：北方的灯光、日出日落、满天繁星等。还有许多新的设备和现象，其中一些我们认为是理所当然的：我们的电脑或电视机的屏幕，或者杂货店的条形码阅读器。如果不是因为许多正在解决等离子体物理问题的科学家的工作，这些设备中的许多就不会存在，而许多人当时认为这些问题并不重要。我们的研究将产生许多电子碰撞截面，将有助于更好地理解低温等离子体中的过程，这对半导体工业或平流层中发生的各种过程都很重要。
