近年来，单原子物理预分离的概念被引入反锕系化学领域。在这种方法中，感兴趣的反锕系元素在物理反冲分离器中分离，然后从该机器中提取。光束以及不需要的反应产物被强烈抑制，从而可以研究以前无法访问的新化学系统。讨论了该技术最重要的方面，并以使用预先分离的同位素进行的一些化学研究为例，介绍了反锕系化学实验的优点。
In recent years, the concept of physical preseparation of single atoms was introduced into the field of transactinide chemistry. In this approach, the transactinide element of interest is isolated in a physical recoil separator and then extracted from this machine. The beam as well as the unwanted reaction products are strongly suppressed, allowing for the investigation of new chemical systems that were not accessible before. The most important aspects of the technique are discussed and the advantages for chemistry experiments with transactinides are presented, using some of the chemical studies that were performed with preseparated isotopes as examples.
