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 ...

Like dancers swirling on the dance floor with bystanders looking on, protons and neutrons that have briefly paired up in the nucleus have higher-average momentum, leaving less for non-paired nucleons.

For the first time, physicists have developed a model that explains the origins of unusually stable magic nuclei based ...

HEISENBERG has discussed the hypothesis that the nucleus of an atom is composed of neutrons and protons only, the neutron being regarded as a fundamental entity and not as a combination of an electron ...

Right now, in our atmosphere, there are countless numbers of nitrogen atoms floating high above the Earth's surface. These atoms are, in a sense, vulnerable. Cosmic radiation, in the form of neutrons, ...

Nuclear physicists have made a new, highly accurate measurement of the thickness of the neutron 'skin' that encompasses the lead nucleus in experiments. The result, which revealed a neutron skin ...

Atoms are very small. They have a radius of around 1 × 10 10 metres. This symbol shows that chlorine has 35 particles in the nucleus (protons and neutrons), 17 of which are protons. It also tells us ...

Neutron stars are the remnants of violent supernovae, all that’s left behind when a star tens of times the mass of our Sun ends its nuclear fuel-burning life. These extreme objects pack more mass than ...
