For the helium-4 nucleus, theorists had until recently perceived the alpha particle as an autonomous and independent system within which nucleons simply move away from each other when the nucleus ...
Only about one helium-3 atom exists for every million helium-4 atoms, Horton said. The team measured about 10 million helium-3 atoms per gram of olivine crystals.
Neutral helium microscopy and atom optics constitute an innovative imaging paradigm that exploits low-energy, charge-neutral helium atoms to non-destructively investigate surface properties at the ...
