Description

Recent studies of the chemical separation and characterization experiments of the first three transactinide elements, rutherfordium (Rf), dubnium (Db) and seaborgium (Sg), conducted one atom at a time in liquid phases, are reviewed. A short description on experimental techniques based on partition methods, specifically automated rapid chemical separation systems, as well as on assessment of role of relativistic effects is also given. Perspectives for liquid-phase chemistry experiments on heavier elements are briefly discussed. (author)

Abstract (Japanese)

超アクチノイド元素,ラザホージウム(Rf),ドブニウム(Db)及びシーボーギウム(Sg)の溶液化学に関する最近の成果を紹介する。核反応で合成されるこれらの元素(核種)は,生成率が小さく半減期も短いため,一度に扱うことができるのはわずか1 原子(シングルアトム)である。シングルアトム化学の概念とそれに基づく分配法による実験の概要,超アクチノイド元素の特徴的な性質と相対論効果との関わりなども併せて解説する。最後に今後の展望を簡単に述べる。(著者)
