Abstract
Method and apparatus for separating isotopes in an isotopic mixture. Photo-excitation of selected isotopic species is utilized in conjunction with various processes including reaction of the excited species with positive ions of predetermined ionization energy, other excited species or free electrons. The products of the reactions include forms of the selected isotopic species which are different than their form prior to excitation, including different mass, charge or chemical make-up. The selected species is then separated from the balance of the reaction products. Ions and electrons are produced by an electrical discharge, and separation is achieved through radial ambipolar diffusion, electrostatic or magnetohydrodynamic techniques.
