Bulletin of the Atomic Scientists
Metallic uranium, vaporized by an electron beam, is illuminated with excitation
and ionization lasers as it passes through the dotted region, thereby selectively
ionizing the uranium-235 atoms. An electric field, E, then sweeps the uranium-
235 ...
If these new, secondary neutrons hit other nuclei of uranium-235, the fission is
repeated. Where there is only a small quantity of uranium- 235, a large proportion
of the new neutrons miss their targets, but it was calculated that if the mass of ...

Uranium has three natural isotopes: uranium-238 (U-238); uranium-235 (U-235);
and uranium-234 (U-234); all of which are radioactive. The relative abundances
of U-238, U-235, and U-234 are 99.28%, 0.71%, and 0.006%, respectively ...
