Seeking a few Postdoctoral Researchers, Contract Researchers, Technical Staffs I or II (W24009)

Laboratory

RIKEN Nishina Center for Accelerator-Based Science
(Director: Hiroyoshi Sakurai)

Research Field

Promoting science and technology related to "element transmutation" founded by Dr. Yoshio Nishina more than 80 years ago, RIKEN Nishina Center for Accelerator-Based Science challenges two ultimate questions: "How are elements created in the universe?" and "Can human beings freely transmute elements?" By returning the research results obtained to society, we are trying to solve the environmental, energy and resource problems faced by humankind.
The Nishina Center operates the RI Beam Factory (RIBF), the world's highest performing heavy ion accelerator facility where radioisotopes that do not exist in nature are artificially created. The Nishina Center promotes researches on the synthesis of superheavy elements with one prime example being nihonium, researches in the fields of magic numbers, nucleosynthesis in the universe, and reducing radioactive waste, as well as theoretical research linking these fields.
