Today, research aimed at the development of low-energy methods of molecular laser isotope separation (MLIS) is relevant and in demand. The main goal of these studies is to find efficient and cost-effective methods that can be used as the basis for the technology of laser separation of uranium isotopes, as well as other elements. To date, a number of approaches to the implementation of low-energy methods of MLIS using infrared (IR) lasers have been proposed. Many of these approaches are not well understood and/or are difficult to put into practice. Some of them are considered to be promising and require further study. These include the method of isotope-selective suppression of the clustering of molecules using IR lasers during gas-dynamic expansion at a nozzle exit and the method of isotope-selective IR dissociation of small molecular van der Waals clusters. A review of recent results obtained using these two methods is presented. The experimental facilities and research methods ar...

使用低能方法进行激光同位素分离的新结果

如今,旨在开发低能分子激光同位素分离(MLIS)方法的研究是相关且有需求的。这些研究的主要目标是找到有效且具有成本效益的方法,这些方法可作为激光分离铀同位素及其他元素的技术的基础。迄今为止,已经提出了使用红外(IR)激光器来实现MLIS的低能量方法的多种方法。这些方法中的许多方法尚未得到很好的理解和/或难以付诸实践。其中一些被认为很有前途,需要进一步研究。这些方法包括在喷嘴出口的气体动态膨胀过程中使用IR激光对分子团簇进行同位素选择性抑制的方法,以及小分子范德华簇的同位素选择性IR离解方法。本文介绍了使用这两种方法获得的最新结果。实验设施和研究方法
