RIKEN Nishina Center for Accelerator-Based Science Superheavy Element Research Group

Director: Hiromitsu Haba (D.Sc.)

Research Summary

Hiromitsu Haba

The heavy elements with atomic numbers exceeding 103 are called superheavy elements (SHEs). In Superheavy Element Research Group, Superheavy Element Production Team and Superheavy Element Devise Development Team work together to investigate synthesis of SHEs, nuclear properties of SHE nuclei, and chemical properties of SHEs. We also develop and maintain SHE production and separation devices, detectors, and chemistry apparatuses.
