The deuteron -- one of the simplest atomic nuclei, consisting of just one proton and one neutron -- is considerably smaller than previously thought, say researchers who measured the proton and found a ...

Precise values for the masses of the nuclei of the simplest atoms, such as hydrogen and helium, are crucial for experiments targeting big unsolved problems in physics. A technique known as ...

Physicists in Germany say they have made the world’s most precise measurement of the deuteron mass by comparing it to the mass of the carbon-12 nucleus. The new work, which was carried out by ...

Have you ever wondered how the Sun creates the energy that we get from it every day and how the other elements beside hydrogen have formed in our universe? Perhaps you know that this is due to fusion ...

High-precision measurements of the mass of the deuteron, the nucleus of heavy hydrogen, provide new insights into the reliability of fundamental quantities in atomic and nuclear physics. This is ...

The latest results from the Relativistic Heavy Ion Collider (RHIC), the world’s most powerful facility for nuclear physics research, strengthen scientists’ confidence that RHIC collisions of gold ions ...

Photon-deuteron collisions offer insight into the gluons that bind the building blocks of matter—and what it takes to break protons and neutrons apart. Scientists have found a way to “see” inside ...

The deuteron — one of the simplest atomic nuclei, consisting of just one proton and one neutron — is considerably smaller than previously thought. This finding was arrived at by an international ...

The puzzle is that the proton—the positively charged particle found in atomic nuclei, which is actually a fuzzy ball of quarks and gluons—is measured to be ever so slightly larger when it is orbited ...

A discrepancy in the measured size of the “deuteron” increases the chance that something is amiss in our understanding of atoms. The same group that discovered a curious discrepancy in measurements of ...
