Elucidation of an electronic state of lawrencium

本研究的目的是通过适用于单离子的电化学方法测定铪 (Lr) 的氧化还原电位。本研究新开发了一种适用于Lr还原的自动化电解柱色谱仪。在准备工作中，首次将0.1 M HCl中的无载体Mo放射性示踪剂从Mo(VI)电解还原为Mo(V)。未来，计划在 JAEA 串列加速器上进行使用该装置的在线还原实验。

The purpose of the present study is to determine the redox potential of lawrencium (Lr) by an electrochemical method available for single ions. In this study, an automated electrolytic column chromatograph apparatus which is applicable to the reduction of Lr was newly developed. In a preparatory work, a carrier-free Mo radiotracer in 0.1 M HCl was electrolytically reduced from Mo(VI) to Mo(V) for the first time. In the future, on-line reduction experiments using the apparatus are planned to be performed at JAEA tandem accelerator.
