Resonant Multiphoton Ionization: Photoelectron Angular Distribution, a Probe of Atomic and Molecular Properties

这是一个理论和实验相结合的项目， 物理化学研究和描述激发的电子 原子和分子的状态。 在实验部分， 偏振光将被用来首先激发，然后再激发 原子和分子。 角分布和能量分布 的光电子将被分析，以确定 在初始激发的电子中， 原子的状态。 对于原子来说， 研究是为了充分描述这种相关性。 一旦 原子被充分描述，现象学理论， 光电子的角分布和能量分布将 扩展到分子，并在实验中进行测试， 角分布和能量分布的研究 从分子中发出的光电子。 这个目标 研究是为了更好地了解 电子和分子核之间的相互作用， 从而更好地理解化学键。

This is a combined theoretical and experimental project in Physical Chemistry to study and describe the excited electronic states of atoms and molecules. In the experimental part, polarized light will be used to first excite and then ionize atoms and the molecules. The angular and energy distributions of the photoelectrons will be analyzed to determine the degree of electron correlation in the initially excited electronic state(s) of atoms. For atoms, the theoretical thrust of this research is to adequately describe this correlation. Once atoms are adequately described, the phenomenological theory of the angular and energy distributions of the photoelectrons will be extended to molecules and experimentally tested in an investigation of the angular and energy distributions of photoelectrons emitted from molecules. The goal of this research is to better understand the dynamics of the interactions between an electron and the molecular core to which it is bound, hence to better understand chemical bonding.
