Outline of Final Research Achievements

We have studied the ion cyclotron resonance method for a separation (enrichment) of stable isotope. The method is based on the relation that the frequency of cyclotron motion in a uniform magnetic field depends only on the mass of particle, and that the cyclotron motion of a specific isotope can be selectively excited by an outside radio-frequecy field which resonates with the cyclotron motion.　The　ICR　method　is　a very unique method, because it can be used for isotope separation of all atoms.
We tried experiments four times using the superconducting solenoid magnet in the Cryoenics Science Center of KEK. We observed a substantial effect for enrichment and yield, 2% and 1 mg/hour, respectively.
