Helium nucleus measured with record precision The results reported by the STAR Collaboration show that the combined information from many such snapshots can be reliably related to the shapes of ...

One mode of decay for uranium is to emit an alpha-particle. This alpha-particle is actually just the heart of a helium atom - its nucleus. Once it has grabbed a couple of electrons, a helium atom has ...

An alpha particle, or helium-4 nucleus, was the subject of a recent German experiment. Since helium-4 only has two protons and two neutrons, theoretical calculations can be used to describe it ...

Nuclear fusion occurs when two light atomic nuclei combine to form a heavier nucleus, releasing vast amounts of energy. This ...

The photoelectric effect involves quantum particles of light (photons) interacting with electrons in atoms, molecules and ...
