Translational light scattering in simple liquids

  • M. Zoppi
Article

Summary

A short review of translational light scattering of simple liquids is reported. The microscopic cross-section is compared with the equivalent expression for neutron scattering experiments (Van Hove, 1954). A survey of the fundamental experiments is reported and the possible application to the study of the dynamics of simple dense systems is analysed. The relevant approximations are critically discussed and the limits of the technique are established. The review mainly deals with classical or almost classical liquids, but also some extensions to quantum systems are considered.

Riassunto

Viene presentato un breve resoconto sullo scattering traslazionale di liquidi semplici. La sezione di scattering microscopica è confrontata con l'equivalente espressione per esperimenti di scattering di neutroni (Van Hove 1954). Viene presentata una discussione critica degli esperimenti più importanti e ne viene analizzata la possibile applicazione allo studio della dinamica microscopica di semplici sistemi densi. Le approssimazioni più rilevanti vengono discusse criticamente e vengono determinati i limiti della tecnica. In questa trattazione vengono considerati perlopiù sisitemi classici o quasi-classici, ma vengono prese in considerazione anche alcune estensioni a sistemi quantici.

Резюме

Предлагается краткий обзор трансляционнго рассеяния света в простых жидкостях. Микроскопическое поперечное сечение сравнивается с эквивалентным выражением для экспериментов по рассеянию нейтронов (Ван Хов 1954). Проводится анализ фундаментальных экспериментов и обсуждается возможное применение для исследования динамики простых систем. Обсуждаются соответствующие приближения и определяются пределы рассматриваемой методики. Обсыждение, в основном, касается классических и почти классических жидкостей, а также рассматриваются некоторые обобщения на случай квантовых систем.
