http://nowaatlantyda.com/2024/04/10/hel-3/ Although there are nine known isotopes of helium (2He) (standard atomic weight: 4.002602(2)), only helium-3 ( He ) and helium-4 ( He ) are stable. All radioisotopes are short-lived, the longest-lived being He with a half-life of 806.92(24) milliseconds. The least stable is He , with a half-life of 260(40) yoctoseconds … See more Helium-2 or He is an extremely unstable isotope of helium. Its nucleus, a diproton, consists of two protons with no neutrons. According to theoretical calculations, it would have been much more stable (although still … See more The most common isotope, He , is produced on Earth by alpha decay of heavier radioactive elements; the alpha particles that emerge are fully ionized He nuclei. He is an unusually stable nucleus because its nucleons are arranged into complete shells. … See more He is stable and is the only stable isotope other than H with more protons than neutrons. (There are many such unstable isotopes, the lightest being Be and B .) There is only a trace amount (0.000002(2)) of He on Earth, primarily present since the … See more Although all heavier helium isotopes decay with a half-life of less than one second, researchers have used particle accelerator collisions to create … See more • General Tables — abstracts for helium and other exotic light nuclei See more

Helium: Fuelling the Future? - Energy Industry Review
WebJun 23, 2024 · 3 He. Helium 3 is a rare isotope of the element Helium, consisting of a nucleus with two protons and one neutron.The approved abbreviation (for physics use) for Helium-3 is 3 He, however, the abbreviation He3 is also seen. Since most of the Earth's helium is produced by alpha-decay of Uranium isotopes, resulting in 4 He (the most … WebIn 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. 4 He forms the bulk of naturally occurring helium, but the lighter isotope 3 He has been formed, since about 1950, in experimentally useful quantities by the decay…. http://hino-service.ru/hino-300-izoterm.html fbry most
