In a preferred embodiment the active medium is a titanium:sapphire crystal and the pump beam is generated by a Nd:YLF laser. One application of the preferred embodiment is for laser isotope separation, for example, for separation of Uranium-235 from gaseous Uranium.Rama Rao...
Uranium pentafluorideUranium 235SeparationParticle sizeElectron microscopyTo aim at a better understanding of the uranium isotope exchange reaction between gaseous UF6 and solid UF5 experiments were done with natural UF6 gas and solid UF5 containing 3% 235U under different pressures of UF6. The ...
Write the symbol for the isotope uranium-235 in the formZAX. Isotope Notation: Isotopes of an element are atoms that have identical atomic numbers, but have different mass numbers. Therefore, their nuclei contains the same numbers of protons, but the numbers of neutrons differ within a small ...

The term “fissile” refers to materials that can sustain chain reactions initiated by low-energy neutrons. The mainfissile isotopesare233U,235U, and239Pu.Natural uraniumcontains 0.72% U-235 and the rest is U-238, which is nonfissile. Isotopic separation processes are used to “enrich” the ...
Uranium-235 was enriched at the end of the chromatogram and 238U was enriched at the front. Two long distance displacement experiments have been carried out, keeping an isotopic plateau region on the chromatogram. Consequently, good accumulation of the isotopic fractionation based on uranous-sulfate...

Concentration of (137)Cs in the black rain streaks is twice as high as fallout deposition on the ground in this area. A (235)U/(238)U atom ratio of 0.00887 was found, which is higher than the natural ratio, reflecting the fact that the atomic bomb "Little Boy" used enriched uranium ...
236U (t½ = 2.34 × 107 years) is an isotope of uranium that is produced by thermal neutron capture of 235U via (n, γ)-reactions and through 238U (n, 3n) 236U reactions with fast neutrons. Even though a small amount of 236U (~35 kg) occurs naturally in the Earth...
