The atomic nucleus is a busy place. Its constituent protons and neutrons occasionally collide, and briefly fly apart with high momentum before snapping back together like the two ends of a stretched ...

Scientists have a new way to use data from high-energy particle smashups to peer inside protons. Their approach uses quantum information science to map out how particle tracks streaming from ...

An international research team has measured neutron form factors with previously unattained precision. All known atomic nuclei and therefore almost all visible matter consists of protons and neutrons, ...

Plasma pinches: From pursuits of nuclear fusion to an attractive point source of accelerated protons for proton radiography.
