Protons are tiny particles just a femtometer across, but without them, atoms wouldn't exist. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

In this video, we explore the existence of neutrons and their transformation into protons. We discuss why free neutrons are ...

Look around you (or, if you’re sight impaired, touch something). Everything solid, liquid, or gas that you see and feel is made of matter. We sometimes call it “normal” matter, though with dark matter ...

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 ...

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 ...

A team of scientists has for the first time measured the elusive weak interaction between protons and neutrons in the nucleus of an atom. They had chosen the simplest nucleus consisting of one neutron ...

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 ...

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 ...

"Electrons will collide with protons or larger atomic nuclei at the Electron-Ion Collider to produce dynamic 3-D snapshots of the building blocks of all visible matter," according to the U.S.

OAK RIDGE, Tenn., Dec. 19, 2018--A team of scientists has for the first time measured the elusive weak interaction between protons and neutrons in the nucleus of an atom. They had chosen the simplest ...
