Studies of Absolute Differential Excitation Cross Sections of Molecular Oxygen by Electron Impact

为了研究高层大气的能量输入，从地面和星载观测平台上观察了来自不同原子和分子的辐射。要分析这些数据，需要基本的信息，即在各种激发条件下获得这些成分发出的光有多容易。这项研究既是一项实验室研究，也是一项理论研究，目的是确定分子氧在4-10 eV范围内所有重要电子跃迁的绝对电子截面。能量损失区。用调制交叉束方法测量不同的截面，并识别解离产物。这些结果将通过广泛的组态相互作用计算来分析，以获得大量状态的势能曲线和偶极跃迁矩。

In order to study the energy input to our upper atmosphere, radiation from the different atoms and molecules is viewed from both ground based as well as space borne observing platforms. To analyze these data requires basic information on how easy it is to get light emitted by these constituents under various excitation conditions. This study is both a laboratory and theoretical study to determine the absolute electron cross- sections for all of the important electronic transitions of molecular oxygen in the 4-10 ev. energy loss region. Differential cross-sections will be measured by a modulated crossed-beam method and the dissociation products will be identified. These results will be analyzed by an extensive configuration interaction calculation to obtain potential energy curves and dipole transition moments from a large number of states.
