Normal helium, which is 700,000 times more common than helium-3, is called helium-4 because it has two protons and two neutrons. Whereas helium-4 is a common product of the decay of radioactive ...

A startup company wants to establish mining operations on the moon to extract a rare isotope needed for future quantum ...

Normal helium, which is 700,000 times more common than helium-3, is called helium-4 because it has two protons and two neutrons. Whereas helium-4 is a common product of the decay of radioactive ...

Whereas helium-4 is a common product of the decay of radioactive elements, helium-3 comes almost entirely from the initial cloud of dust and gas that formed the solar system. This primordial ...

These results suggest that similar reactions between helium and iron may have occurred within Earth’s core shortly after its formation, trapping much of the primordial helium-3 in the material that ...

Four existing discoveries at Galactica/Pegasus (JXSN-1 to JXSN-4) have delivered gas flows of 125 to 412 thousand cubic feet per day ("Mcfd") to 412 Mcfd with high helium concentrations of between ...

That is, helium, which differs from normal helium, or 4 He, so called because it contains two protons and two neutrons and is continuously produced by radioactive decay.
