Solar System Laboratory Aeronomy by Electron Impact with Emphasis on Terrestrial Processes

这些研究人员继续研究原子和分子结构的基本性质以及对高空气象学感兴趣的反应。 这项工作将实验室天体物理学与基本速率过程模型相结合，为高层大气学和行星大气社区提供了广泛适用的方法。 PI将专注于原子氮，分子氮和氧的电子激发和光子吸收特性。 总而言之，他将：（1）进行高分辨率吸收测量以获得精确的旋转相关电偶极矩，应用于高分辨率发射测量以精确定义带跃迁中的预解离损失;（2）测量对高层大气物理学重要的电子激发截面，并建立氧碰撞和辐射系统的模型结构;（3）建立了测量氮原子电子碰撞截面的实验装置和相应的原子模型;（4）重新检验了氮分子的电离-激发截面，并与现有的精确光电离数据相一致。

These investigators continue research in basic properties of atomic and molecular structure and reactions of interest to aeronomy. The work combines laboratory astrophysics with basic rate process models to provide broadly applicable methodology for the aeronomy and planetary atmospheres' communities. The PI will focus on electron excitation and photon absorption properties of atomic nitrogen, molecular nitrogen, and oxygen. In sum, he will: (1) perform high resolution absorption measurements to obtain accurate rotationally dependent electric dipole moments, applied to high resolution emission measurements for accurate definition of predissociation loss in band transitions; (2) measure electron excitation cross sections important to aeronomy, and establish a model structure for oxygen collisional and radiative systems; (3) establish an experimental setup for measuring atomic nitrogen electron impact cross sections, with an accompanying atomic model; and (4) reexamine the ionization-excitation cross sections of molecular nitrogen, and reconcile with existing accurate photoionization data.
