For three months in 2019, physicists blasted a beam of electrons at lead atoms that were held in place by foil made of diamond. The team was trying to determine the thickness of the neutron skin, the ...

The precise measurement of an exotic atom in the laboratory has refined scientists’ understanding of neutron stars, which are among the universe’s most extreme objects. The study, published January 22 ...

Physicists have measured the “skin” of an atom for the first time and, perhaps unsurprisingly, it is extremely thin. The measurement may help us understand the properties of neutron stars. Lead-208, ...

Some atomic nuclei are thin-skinned — they’re surrounded by a slim shell of neutrons. Physicists now know how thick that neutron skin is for one particular type of nucleus. The skin of lead-208 — a ...

Neutrons have a huge amount of potential to advance science in various fields. To produce the free neutrons needed for scientific experimentation, a new facility is being constructed in Sweden. The ...

Neutron scattering studies of "cobalt blue," a compound prized by artists for its lustrous blue hue, are revealing unique magnetic characteristics that could answer questions about mysterious ...

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.
