For the research, Dygert and his team looked into the distribution of two very specific noble gas isotopes: Helium-3
The prize potentially on offer is the extraction of Helium-3
, a variant of the everyday helium found in balloons.
In the 1970s scientists discovered that helium-3
, a rare isotope of the element, also has a superfluid state at temperatures lower than 2 millikelvins.
Ouyang Ziyuan, head of lunar exploration, outlined plans to exploit the vast quantities of helium-3
thought to lie buried in lunar rock.
Our detector design builds on the success of a segmented helium-3
ionization chamber and a neutron MicroMegas detector.
Fusion researchers have long been interested in the possibility of using the fusion of deuterium with helium-3
rather than with tritium because of the radioactivity associated with the deuterium-tritium fuel cycle.
Scientists believe they have found vast areas of Helium-3
gas, and have drawn up maps to guide Moon prospectors.
In 1962 the German-born British physicist Heinz London (1907-1970) used a mixture of the two helium isotopes helium-4 and helium-3
for the purpose.
Packard, heard a whistle from reservoirs of helium-3
separated by a sieve like membrane (SN: 8/2/97, p.
Then, in 1972, experimenters found that a rare isotope of helium known as helium-3
also becomes a superfluid.
The article states that the "concentration of radioactive helium-3
isotopes" in rocks suggests information about the history of the rocks.
