Discover the foundational components of an atom: protons, neutrons, and electrons. This video delves into the traditional atom model and reveals its inaccuracies, particularly regarding electron ...

The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...

Physicists have discovered a surprising new “Island of Inversion” in a place no one expected: among nuclei where the number of protons equals the number of neutrons. For decades, these strange regions ...

Matter is a lush tapestry, woven from a complex assortment of threads. Diverse subatomic particles weave together to fabricate the universe we inhabit. But a century ago, people believed that matter ...

Physicists have found a new “island of inversion” in the nucleus of molybdenum-84, a perfectly balanced atom with equal numbers of protons and neutrons. The discovery upends a decades-old assumption ...

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 ...

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 researcher stands behind a metal pipe covered with electrical cords and gauges. A researcher works on a device at the Facility for Rare Isotope Beams. This part of the facility provides low-energy ...
