An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

Just as an electron orbiting a nucleus makes its own magnetic moment, charged constituent particles inside a single proton (or neutron) will contribute to the proton's (or neutron's) magnetic ...

A rather unassuming particle is playing an important role in the hunt for subatomic oddities. Similar to protons and neutrons ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic ...

It’s a case of acting differently when outmanned — or rather out-neutroned. Protons appear to get extra pep in their step when they’re outnumbered by neutrons in the atom’s nucleus. A new study ...

The researchers looked for signs of proton and neutron pairs in atoms of carbon, aluminum, iron, ... (Continuous Electron Beam Accelerator Facility) Large Acceptance Spectrometer, ...

But since there is somewhere around 1 extra proton (or neutron) for every 1.4 billion proton/antiproton pairs, we're left over with a small excess of protons and neutrons.

Scientists have long wondered whether there is a limit to the number of protons and neutrons that can be clustered together to form the nucleus of an atom. A new study comes closer than ever to ...

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 ...

We detected the scattered electron and the scattered proton or neutron," Duer explains. ... That is, protons and neutrons both prefer to pair with particles different from themselves by 20 to 1.
