In nuclear physics, "magic numbers" identify specific numbers of protons or neutrons that lead to especially stable nuclei.

Fifty experts on nuclear physics, particle physics and astrophysics met at CERN from 9 to 13 June to discuss how to use ...

Charge-symmetry breaking also manifests itself in the interactions of pions with protons and neutrons in a very interesting way that is linked to the neutron-proton (and hence, up and down quark) mass ...

Standard model gets right answer for proton, neutron masses Correct calculation strengthens theory of quark-gluon interactions in nuclear particles ...

Rutherford also put out the idea that there could be a particle with mass but no charge. He called it a neutron, and imagined it as a paired proton and electron.

Neutrons are subatomic particles with no electrical charge, and a slighter higher mass than a proton. Due to quantum degeneracy pressure neutron stars are supported against further collapse.

Losing the positive charge turns one of the protons into a neutral neutron, and together the proton and neutron form deuterium (an isotope of hydrogen).

It is assumed that an undiscovered “fifth force” likely exists between neutrons in an atom’s nucleus and the electrons ...

A dense, collapsed star spinning 707 times per second—making it one of the fastest spinning neutron stars in the Milky Way galaxy—has shredded and consumed nearly the entire mass of its ...
