ABSTRACT:
A method comprises revolving liquid UF.sub.6 in a swinging bucket rotor or a fixed angle rotor of an ultra centrifuge with a peripheral velocity of 300 m/s or above and at a speed of 40,000 to 65,000 rpm or above, providing force from 240,660 g to 485,000 g or above. The method yields a separation of the U.sup.235 F.sub.6 and U.sup.238 F.sub.6 isotopes.
