Kegunaan isotop neon
- Neon is subject to stable isotopic fractionation by physical processes, such as exchange between gas, liquid, and solid phases. Small variations in the isotope-amount ratio n(22Ne)/n(20Ne) have been used to examine gas-liquid exchange processes during groundwater recharge (water moving downward from the surface) and discharge,,.
- Masers (Microwave Amplification by Stimulated Emission of Radiation) containing 20Ne have been used to study quantum physics. 21Ne may also play a role in maser studies of quantum physics.
- 22Ne is used to produce the radioisotope 22Na via the reaction 22Ne (p, n) 22Na. 20Ne has been used to produce the radioisotope 18F via the reaction 20Ne (d, 4He) 18F.
