Superheavy Element Laboratory
Research Areas
|
The elements with their atomic number Z>103 are called as trans-actinide or superheavy elements. The chemical properties of those elements have not yet been studied in detail. Those elements are not exist in nature therefore, they must be produced by artificially for the scientific study of those elements. In our laboratory, we have been studying the physical and chemical properties of the superheavy elements utilizing the accelerators in RIKEN and various methods of efficient production of the superheavy elements.
