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 ...

The positively charged particles may have an outsize influence on the properties of neutron stars and other neutron-rich objects. Neutron stars are the smallest, densest stars in the universe, born ...

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 ...

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 ...

The next time you step on bathroom scales, remember that it’s not your big bone structure or that extra helping of pudding that makes you heavy, it’s the motion of the quarks and gluons buzzing around ...

Adding a single proton to a doubly magic isotope of oxygen is enough to significantly alter its properties, an international team of physicists has discovered. Led by Tsz Leung Tang at the University ...

The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce ...

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, ...

When it comes to weighty matters, quarks and gluons rule the universe, a new study confirms. One of the largest computational efforts to calculate the masses of protons and neutrons shows that the ...

Proton therapy has emerged as a highly precise modality in radiotherapy, utilising accelerated proton beams to deposit dose in a controlled manner and thereby spare surrounding healthy tissues.

CAMBRIDGE, MA -- Neutron stars are the smallest, densest stars in the universe, born out of the gravitational collapse of extremely massive stars. True to their name, neutron stars are composed almost ...
