线偏振光的瑞利散射:完整实验方案

Rayleigh scattering of a linearly polarized light: scenario of the complete experiment

A. V. Volotka, A. Surzhykov, S. Fritzsche

摘要:

研究了光子在原子上的弹性散射过程,即瑞利散射。表达的电磁复杂的散射振幅的散射可观测量,我们工作的情况下,他们的独立基准的实验。特别地,初始线性偏振光的横截面和偏振转移的组合为除了固定散射角之外的任何散射角的完整实验提供了机会。它使我们能够推导出的电和磁的振幅与相位差分别模。通过150 - 250 keV光子在铅原子上散射的理论计算说明了这一发现。

英文摘要:

The process of the elastic scattering of photons on atoms, known as the Rayleigh scattering, is investigated. Expressing the scattering observables in terms of the electric and magnetic complex scattering amplitudes, we work over the scenarios for their independent benchmarking by experiments. In particular, the combination of the cross section and polarization transfer of initially linearly polarized light provides an opportunity for a complete experiment for any but fixed scattering angle. It allows us to deduce the modulus of the electric and magnetic amplitudes together with the phase difference individually. The findings are illustrated by the theoretical calculations of the scattering of 150 - 250 keV photons on lead atoms.
