An international research team led by the Paul Scherrer Institute PSI has measured the radius of the nucleus of muonic helium ...

The new paper proposes that if a helium nucleus accelerates in the jet of a supermassive black hole, it crashes into photons and breaks apart, spilling its two protons and two neutrons into space. The ...

A puzzling discovery in NGC 1068 shows a flood of neutrinos but weak gamma rays. Scientists now suspect helium atoms ...

An international research team including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI ...

End of 2022, researchers at the NIF succeeded in generating more energy with a fusion reaction than they put into it. Now there are new records.

If the number of neutrons N is 2 then there must be 4 - 2 = 2 protons. There are 2 protons in the helium nucleus. If the atom loses one or more electrons, it will have more protons than electrons ...

So in the helium example, there would be four protons and two electrons in the nucleus to yield a mass of 4 but a charge of only 2. Rutherford also put out the idea that there could be a particle ...
