Low-Energy Vibrational Excitation of Molecules by Electron Impact (Physics)

理论研究提出了激发的一个 电子的入射能量接近分子 这种兴奋的门槛。 有严重的矛盾 实验，包括观察到的无法解释的 门槛结构 整个系统的量子物理 输入这些过程的描述。 这里的目标是 发展了该领域的散射理论。 有 调查的三个主要组成部分。 (1)发展 无参数模型极化/相关势。（二） 新的近似理论处理方法的发展 近阈值碰撞的量子动力学 (3)考试 现有的理论和 低能激发的实验截面。

Theoretical studies are proposed of the excitation of a molecule by an electron whose incident energy is near the threshold of that excitation. There are serious discrepancies with experiment, including the observation of unexplained threshold structures. The full quantum physics of the system enters the description of these processes. The goal here is the development of a scattering theory for this domain. There are three main components of the investigation. (1) Development of parameter-free model polarization/correlation potentials. (2) Development of new approximate theoretical treatments of the quantum dynamics of near-threshold collisions. (3) Examination of the discrepancies between existing theoretical and experimental cross sections for low-energy excitations.
