  2. Atomic vapor laser isotope separation - Wikipedia

    en.wikipedia.org/wiki/Atomic_vapor_laser_isotope...

    An atomic vapor laser isotope separation experiment at LLNL. The green light is from a copper vapor pump laser used to pump a highly tuned dye laser which is producing the orange light. Atomic vapor laser isotope separation , or AVLIS , is a method by which specially tuned lasers are used to separate isotopes of uranium using selective ...

  3. Laser isotope separation - Wikipedia

    en.wikipedia.org/wiki/Laser_isotope_separation

    Laser isotope separation, or laser enrichment, is a technology of isotope separation using selective ionization of atoms or molecules by the means of precisely tuned lasers. The techniques are: Atomic vapor laser isotope separation (AVLIS), applied to atoms; Molecular laser isotope separation (MLIS), applied to molecules

  4. Separation of isotopes by laser excitation - Wikipedia

    en.wikipedia.org/wiki/Separation_of_isotopes_by...

    Infrared absorption spectra of the two UF 6 isotopes at 300 and 80 K. Schematic of a stage of an isotope separation plant for uranium enrichment with laser. An infrared laser with a wavelength of approx. 16 μm radiates at a high repetition rate onto a UF6 carrier gas mixture, which flows supersonically out of a laval nozzle.

  5. Isotope separation - Wikipedia

    en.wikipedia.org/wiki/Isotope_separation

    Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes. The use of the nuclides produced is varied. The largest variety is used in research (e.g. in chemistry where atoms of "marker" nuclide are used to figure out reaction mechanisms).

  6. Isotope fractionation - Wikipedia

    en.wikipedia.org/wiki/Isotope_fractionation

    Isotope fractionation occurs during a phase transition, when the ratio of light to heavy isotopes in the involved molecules changes. When water vapor condenses (an equilibrium fractionation), the heavier water isotopes (18 O and 2 H) become enriched in the liquid phase while the lighter isotopes (16 O and 1 H) tend toward the vapor phase.

  7. Molecular laser isotope separation - Wikipedia

    en.wikipedia.org/wiki/Molecular_laser_isotope...

    Molecular laser isotope separation (MLIS) is a method of isotope separation, where specially tuned lasers are used to separate isotopes of uranium using selective ionization of hyperfine transitions of uranium hexafluoride molecules. It is similar to AVLIS. Its main advantage over AVLIS is low energy consumption and use of uranium hexafluoride ...

  8. Hydrogen isotope biogeochemistry - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_isotope...

    The amount of liquid-vapor equilibrium fractionation for hydrogen isotopes is about 8x that of oxygen isotopes at Earth surface temperatures, which reflects the relative mass differences of the two isotope systems: 2 H is 100% heavier than 1 H, 18 O is 12.5% heavier than 16 O. Above the boundary layer, there is a transition zone with relative ...

  9. Gas centrifuge - Wikipedia

    en.wikipedia.org/wiki/Gas_centrifuge

    Diagram of a gas centrifuge with countercurrent flow, used for separating isotopes of uranium. A gas centrifuge is a device that performs isotope separation of gases. A centrifuge relies on the principles of centrifugal force accelerating molecules so that particles of different masses are physically separated in a gradient along the radius of a rotating container.
