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 ...
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 ...
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, ...

A type of hydrogen that doesn't interact with light could explain how long neutrons live and reveal the identity of the universe's dark matter, according to a new theory. When you purchase through ...
A study of bound protons and neutrons conducted at the Department of Energy's Thomas Jefferson National Accelerator Facility has allowed scientists, for the first time, to extract information through ...
