WebApr 1, 2000 · Helium is abundant in space, where it's produced as a product of the fusion reaction inside stars such as the sun. The naturally occurring helium on Earth, though, comes from a different sort of process. Deep inside the Earth, radioactive elements such … A perfect vacuum weighs zero grams, so a liter of perfect vacuum weighs 0.18 … WebA helium-3 atom is a fermion and at very low temperatures, they form two-atom Cooper pairs which are bosonic and condense into a superfluid.These Cooper pairs are substantially larger than the interatomic separation. …

WebSome stable helium-3 is produced in fusion reactions from hydrogen, but it is a very small fraction, compared with the highly energetically favorable production of helium-4. The stability of helium-4 is the reason that hydrogen is converted to helium-4, and not deuterium (hydrogen-2) or helium-3 or other heavier elements during fusion reactions ... fishing odessa texas
