Times Cited Count：7 Percentile：20.98(Chemistry, Physical)We use the newly developed non collinear spin polarized density functional method to describe the tetrachlorides of element Rutherfordium (Rf) and its homologues. It is the first time that a real three-dimensional molecule is described with this method. Without any additional corrections (used so far for the atomic values) we get nearly complete agreement for all homologues and thus a good prediction for the unknown value for RfCl.

Elements in the heavy region of the periodic table, with atomic numbers exceeding 100, are subject to significant relativistic effects on their electron orbitals due to their large nuclear charge. This might cause their chemical properties to deviate from periodic trends. However, these heavy and superheavy elements (SHEs) can only be synthesized through heavy-ion nuclear reactions, and the resulting nuclides are all short-lived radioisotopes. Therefore, only one or a few atoms can be handled at a time, leaving many aspects of their chemical properties unveiled. At the Japan Atomic Energy Agency (JAEA), we have been studying to clarify the chemical properties of these heavy and superheavy elements to better understand the role of relativistic effects. Our research combines radiochemical techniques with online methods, such as rapid chemical separation techniques in both gas and liquid phases. By integrating an online isotope separation technique, we have achieved notable progress. The presentation will provide an overview of the results obtained at JAEA to date, along with a discussion of our future plans, including the use of new approaches such as ion trap chemistry.
