Helium-3 (3 He, see also helion) is a light, non-radioactive isotope of helium with two protons and one neutron (common helium having two protons and two neutrons). Its hypothetical existence was first proposed in 1934 by the Australian nuclear physicist Mark Oliphant while he was working at the University of Cambridge Cavendish Laboratory.


Mining Helium-3 on the Moon. One of many problems associated with using helium-3 to create energy via nuclear fusion is that, at least on the Earth, helium-3 is very, very rare indeed. Helium-3 is produced as a by-product of the maintenance of nuclear weapons, which could net a supply of around 15Kg a year.


Background and History. Everyone learns about Helium in school. It is the second element in the periodic table having 2 protons, 2 neutrons and 2 electrons - having an atomic mass of 4.But another form of Helium has been in the news lately and it is called Helium-3.


Helium-3 (He-3) is a light, non-radioactive isotope of helium with two protons and one neutron. It is rare on Earth, and it is sought for use in nuclear fusion research. The abundance of helium-3 is thought to be greater on the Moon (embedded in t...


Mining the moon for helium-3 would offer a unique opportunity to acquire those resources as byproducts. Other opportunities might be possible through the sale of low-cost access to space.


Some stable helium-3 (2 protons and 1 neutron) is produced in fusion reactions from hydrogen, but it is a very small fraction compared to the highly favorable helium-4. Binding energy per nucleon of common isotopes. The binding energy per particle of helium-4 is significantly larger than all nearby nuclides.


One of the main reasons helium-3 is sought as a fusion fuel is because there are no neutrons generated as a reaction product. The protons that do get generated have charge, and can therefore be ...


Helium 3 (He-3) is a light, non-radioactive isotope of helium with two protons and one neutron. Its presence is rare on Earth, but it is sought after for use in nuclear fusion research.


Helium-3 (3 He) is a rare stable isotope of helium and is commercially available in isotopically separated form. Read More; superfluid research. In superfluidity: Discovery …stable isotopes of helium are helium-3 (or 3 He), with two protons and one neutron, and helium-4 (or 4 He), with two protons and two neutrons.


He has created a small reactor at the Fusion Technology Institute, but so far it has not been possible to create the helium fusion reaction with a net power output. This has not stopped the search for Helium-3 from being a motivating factor in space exploration, however.
