This project will continue investigating excitation cross section measurements of molecular oxygen by electron impact. Previously, the PI studied the Schumann-Runge continuum, and longest and second bands. Under this proposal, the pseudo-continuum region will be studied. This program will determine absolute electron impact cross sections for all the important electronic transitions of molecular oxygen in the pseudo-continuum region. Differential cross sections for excitation of the identifiable electronic states in this region will be measured by a crossed-beam method.***

该项目将继续研究电子碰撞下分子氧的激发截面测量。此前，PI研究了舒曼-龙格连续体，以及最长和第二个频带。在这一建议下，将研究伪连续区域。该程序将确定准连续区域中分子氧的所有重要电子跃迁的绝对电子碰撞截面。将用交叉束方法测量该区域可识别电子态的激发的微分截面。
