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。有些已经吸引了几个世纪的人：北极光，日出和日落，夜空充满了星星等也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，或在杂货店的条形码阅读器。许多这样的设备将不存在，如果不是许多科学家的工作谁是解决问题的等离子体物理，许多人会认为不重要的时间。我们的研究将产生许多电子碰撞截面，这将有助于更好地了解低温等离子体中的过程，这些过程对半导体工业或平流层中发生的各种过程都很重要。
