[1] [2] 129 Xe is a stable, naturally occurring isotope of xenon with 26.44% isotope abundance. It is one of two Xe isotopes, along with 131 Xe, that has non-zero spin, which allows for magnetic resonance. 129 Xe is used for MRI because its large electron cloud permits hyperpolarization and a wide range of chemical shifts
A xenon arc lamp is a highly specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure. It produces a bright white light to simulate sunlight , with applications in movie projectors in theaters , in searchlights , and for specialized uses in industry and research.
The ratio of xenon-136 to xenon-135 (or its decay products) can give hints as to the power history of a given reactor and the absence of xenon-136 is a "fingerprint" for nuclear explosions, as xenon-135 is not produced directly but as a product of successive beta decays and thus it cannot absorb any neutrons in a nuclear explosion which occurs ...
Spin exchange optical pumping (SEOP) [3] is one of several hyperpolarization techniques discussed on this page. This technique specializes in creating hyperpolarized (HP) noble gases, such as 3 He, 129 Xe, and quadrupolar 131 Xe, 83 Kr, and 21 Ne. [4] Noble gases are required because SEOP is performed in the gas phase, they are chemically inert, non-reactive, chemically stable with respect to ...
Gas strobe beacons include Xenon flash lamp and halogen varieties. Gas strobe beacons consist of a gas-filled tube surrounded by a lens. When electricity is applied, the tube flashes and is magnified by the lens, and a 360 degree light is emitted. The intensity of the light depends on the amount of electricity provided. [3] [4]

Xenon lamp may refer to: Xenon arc lamp; Xenon flash lamp; An incandescent light bulb filled with xenon gas to improve life span or efficiency;
The power level of the lamps is rated in watts/area, total electrical input power divided by the lamp's inner wall surface. Cooling of the electrodes and the lamp envelope is of high importance at high power levels. Air cooling is sufficient for lower average power levels.
