Osaka, Japan - The nuclear force that holds protons and neutrons together in the center of atoms has a non-central component -- the tensor force, which depends on the spin and relative position of the ...

IN order to use the results of experiments on the scattering of high-energy neutrons by protons to obtain information about nuclear interactions, it is necessary to calculate the expected angular ...

The interactions of the quarks and gluons that make up protons and neutrons are so strong that the structure of protons and neutrons is difficult to calculate from theory and must be instead measured ...

Researchers at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Lab (BNL) in the US have discovered that when spinning protons collide with nuclei they produce neutrons that fly-off ...

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 ...

The behavior of water molecules in proton-conducting materials is critical for understanding and exploiting their features. This entails being able to take very quick shots to detect changes in water ...

In the 1940s, researchers discovered that neutrons could serve as tools for measuring nuclear properties and determining the atomic and magnetic structures of materials. The first nuclear reactors, ...

Unless you're interested in isotopic labeling, neutrons don't figure much into chemistry. Neutral in charge and a bit bigger than a proton, the neutron neither gives an atom its name nor determines ...

An international team of researchers at the US Department of Energy's Jefferson Accelerator Laboratory in Virginia has measured the weak charge of the proton for the first time. Although first ...

The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...

An international research collaboration has reported the first experimental evidence that the strongly correlated proton-neutron pairs found in an atomic depend on nuclear structure. The experiment, ...
