Outline of Final Research Achievements

Highly efficient isotope separation technology is required for annihilation disposal of radioactive cesium by nuclear transmutation. From the viewpoint to accelerate researches for laser isotope separation and its irreversible collection processes, we developed fundamental technologies with a focus on Doppler-free laser spectroscopy for plasmas. In the course of the research for laser absorption spectroscopy under high pressure, we also found new isotope separation scheme for radioactive cesium which is superior to previous suggestions for realization.
