Abstract

Heavy elements beyond mendelevium (101Md) are usually available in quantities of only a few atoms at a time for experiments, and so studies on their chemical properties have to be performed based on the single atom chemistry with an accelerator online experiment. Therefore, chemical properties of the so-called superheavy elements are little known and remain to be further investigated. The synthesis of Element 113 in RIKEN demonstrates that full studies of superheavy elements are indeed underway in Japan. Recently we found some new chemical properties of rutherfordium (104Rf) at JAERI. Here we have briefly demonstrated the fascinating studies involved in probing the structure of the periodic table at its uppermost end, where relativistic effects drastically influence chemical properties. As well, the present status of chemical studies on superheavy elements in Japan is reviewed, and some research plans for the near future are briefly discussed.
