光子和电子与原子相互作用中极化的原子理论方法

Atomic theory methods for the polarization in photon and electron interactions with atoms

A. Kupliauskiene

摘要:

本文提出了一种不同于密度矩阵的方法,用于推导极化原子与极化光子和极化电子相互作用的一般表达式。描述所有参与该过程的粒子的极化状态的横截面的表达式是通过不可约张量以展开的形式获得的,不可约张量在方向变化下具有最简单的可能行为。适用于特定的实验条件的一般表达式的应用程序的方式进行了概述,通过推导光电子和俄歇电子的角分布的不对称参数以下光电离,以及光和俄歇电子之间的角相关参数。

英文摘要:

An alternative method to the density matrix formalism for the derivation of general expressions of the interaction of polarized atoms with polarized photons and electrons is presented. The expression for the cross-section describing the polarization states of all particles taking part in the process are obtained in the form of an expansion via irreducible tensors that have the most simplest possible behaviour under changes of directions. The ways of the application of the general expressions suitable for the specific experimental conditions are outlined by deriving asymmetry parameters of the angular distributions of photoelectrons and Auger electrons following photoionization as well as the parameters of the angular correlations between photo- and Auger electrons.
