ABSTRACT:
The isotope U.sup.235 is separated from a gasified isotope mixture of U.sup.235 and U.sup.238 by selectively exciting the U.sup.235 from the ground state utilizing resonant absorption of radiation from precisely tuned lasers. The excited isotope is then selectively ionized by electron bombardment. It then is separated from the remaining isotope mixture by electromagnetic separation.
