OAK RIDGE, Tenn. — Examining the smallest parts of the universe often takes the biggest kinds of equipment. At Oak Ridge National Laboratory, a unique piece of equipment the size of a building is ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

An experiment at the Brookhaven National Laboratory (BNL) in the United States provides new insights into the strong interaction that holds neutrons and protons together inside atomic nuclei 1.

Known as “islands of inversion,” these regions are found among a sea of normal nuclei. Now, a new island may have been ...

According to the classical model of nuclear structure, the internal structure of nucleons should not change if they are bound into atomic nuclei. But it was discovered 35 years ago that quarks inside ...

If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...

Protons in neutron-rich nuclei have a higher average energy than previously thought, according to a new analysis of electron scattering data that was first collected in 2004. The research appears to ...

Scientists have discovered a new way to investigate the structure of protons using neutrinos, known as 'ghost particles.' Neutrinos are one of the most abundant particles in our universe, but they are ...

An international team of researchers recently measured the lifetime of a neutron outside of an atomic nucleus with extraordinary precision. By their measurements, the neutron survived for 14.629 ...

Physicists are drawing closer to answering a long-standing mystery of the universe: how long a neutron lives. Neutrons are electrically neutral particles that usually combine with protons to make up ...

HEISENBERG has discussed the hypothesis that the nucleus of an atom is composed of neutrons and protons only, the neutron being regarded as a fundamental entity and not as a combination of an electron ...
