Physical properties. Because of its low atomic mass of 3.02 atomic mass units, helium-3 has some physical properties different from those of helium-4, with a mass of 4.00 atomic mass units. Because of the weak, induced dipole–dipole interaction between the helium atoms, their microscopic physical properties are mainly determined by their zero-point energy.


Other articles where Helium-3 is discussed: mass spectrometry: Development: …a cyclotron to demonstrate that helium-3 (3He) was stable rather than hydrogen-3 (3H), an important question in nuclear physics at the time. They also showed that helium-3 was a constituent of natural helium. Their method was the same as that described above for the omegatron except that a full-sized cyclotron…


For helium-3 to form a superfluid, it must be cooled to a temperature of 0.0025 K, or almost a thousand times lower than helium-4 (2.17 K). This difference is explained by quantum statistics , since helium-3 atoms are fermions , while helium-4 atoms are bosons , which condense to a superfluid more easily.


Helium-3 is an isotope of helium that is used in nuclear fusion reactors, and as fuel for "fusion torches", which are the main commercial form of starship thruster.For this reason, it is a key resource in the galactic economy. Helium-3 can often be found in the atmospheres of gas giants, from where it can be easily and cheaply skimmed.


Question: What is the mass of helium-3 (in MeV/c2 )?(There is no need to enter units). 2.8094


The mass of He-4 is going to be less than the mass of the constituents, because the system is bound together, and energy must be released for this to happen. In the case of He-4, this is about 28.3 MeV, which has a mass equivalent of 0.0304 atomic mass units


Being one of the lightest elements in the world, Helium has an atomic mass of 4.0026 u. u means Unified Atomic Mass Units. 1 u equals to the mass of 1/12 of the mass of a 12C ( Carbon - 12 ) isotope. Carbon isotope is considered as the landmark he...


The real hurdles they face are not the bureaucratic red tape or even the logistics of a mass space and mining effort, but rather the physics of helium-3 fusion itself. In other words, is helium-3 ...


Detailed decay information for the isotope helium-3 including decay chains and daughter products.


Helium-3 (He-3) is a light, non-radioactive isotope of helium with two protons and oneneutron, in contrast with two neutrons in common helium.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.
