Scientists have used CERN's Large Hadron Collider (LHC) to uncover what they say is an entirely new type of particle, dubbed ...

The structure of a neutron or a proton is modified when the particle is bound in an atomic nucleus. Experimental data suggest an explanation for this phenomenon that could have broad implications for ...

Add Yahoo as a preferred source to see more of our stories on Google. The linear accelerator at the Facility for Rare Isotope Beams, where researchers study rare isotopes of elements. Facility for ...

Fast-moving protons are much more likely to pair up with fast-moving neutrons than with other protons in the nuclei of atoms, according to a recent experiment. The research confirms a previous ...

Whereas some people play extreme sports, many nuclear physicists seek the thrill of extreme isotopes, by finding, for each chemical element, the largest possible number of neutrons that can be held by ...

A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest building blocks in nature: atomic nuclei. In new research published in Nature ...

New research has found that protons are about 20 times more likely to pair up with neutrons than with other protons in the nucleus. The result, based on the first-ever simultaneous measurement of such ...

The new particle, named Xi-cc-plus, carries two heavy charm quarks and is about four times heavier than an ordinary proton.

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.

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 ...

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 ...

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 ...
