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 ...

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 ...

i know a neutron is made of two down quarks and one up quark and yet the neutrino is made up of electron neutrino, muon neutrino and tau neutrino. Click to expand... The neutron is a composite entity; ...

Neutron star collisions are known to be factories in which heavy elements are produced. The fusion that takes place inside stellar cores can only produce elements up to iron; the r-process, or ...

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, ...

Atoms can be more overweight than we thought, a team of scientists in the United States has discovered. They have sent atoms crashing into one another in a particle accelerator to create bloated ...

Fundamental physics, as we've seen, finds itself in a difficult situation. Nothing unexpected has turned up at the Large Hadron Collider. We have phenomena like dark matter and dark energy that are ...
