Absolute Electron Impact Cross Sections for Atmospheric Species

大气成分的电子激发发生在地球、主要行星及其某些卫星和其他物体（如彗星）的大气中。与周围大气物种的光电子碰撞以及地球极光带和其他行星某些区域的加速电子的影响都是重要的。该奖项是美国国家科学基金会目前的一项为期三年的航空资助的更新，该资助的重点是开发测量不稳定大气物种（主要是原子氧）的实验室电子截面的技术。

Electron excitation of atmospheric constituents takes place in the atmospheres of Earth, the major planets and certain of their satellites, and other objects such as comets. Both photoelectron collisions with the ambient atmospheric species as will as impact of accelerated electrons in the auroral zones of the Earth and in certain regions on other planets are important. The award is a three-year renewal of a current NSF Aeronomy grant whose focus is to develop the techniques to measure the laboratory electron cross sections for unstable atmospheric species, principally atomic oxygen.
