From a research paper: “Probing Cold Dense Nuclear Matter”: The protons and neutrons in a nucleus can form strongly correlated nucleon pairs. Scattering experiments, where a proton is knocked-out of ...

Physicists peering inside the neutron are seeing glimmers of what appears to be an impossible situation. The vexing findings pertain to quarks, which are the main components of neutrons and protons.

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 ...

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 ...

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 ...

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 ...

In the world of nuclear physics, protons often take the spotlight. But now, for the first time, the neutron has stepped into it. A recent experiment using the U.S. Department of Energy’s Jefferson Lab ...

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 ...

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 ...

A new study carried out at the Department of Energy's Thomas Jefferson National Accelerator Facility has confirmed that increasing the number of neutrons as compared to protons in the atom's nucleus ...

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, ...
