Since the atomic nucleus was first proposed in 1911, physicists simply assumed it was round. ​ But are the nuclei of atoms ...

More than 100 years after scientists began studying the atomic nucleus, they still don’t understand what holds it together. The nuclear force is the strongest force in the universe, yet it ...

T he atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to ...

Atomic nucleus excited with laser: a breakthrough after decades The 'thorium transition', which has been sought after for decades, has now been excited for the first time with lasers. This paves ...

(via Sabine Hossenfelder) I used to think that atomic nuclei are basically little balls, but this paper which just appeared found one that's the shape of a dumbbell. And it's not even a highly ...

An international research team led by the Paul Scherrer Institute PSI has measured the radius of the nucleus of muonic helium ...

Our collection of antimatter has just gotten heavier, as researchers have logged the heaviest antimatter version of an atomic nucleus yet, called antihyperhydrogen-4. “We didn’t think that it ...

Causing energy jumps in a nucleus requires a much higher frequency signal than is required for atomic clocks. With more wave cycles per second, this approach is expected to provide more accurate ...

Subtle quantum effects within atomic nuclei can dramatically affect how some nuclei break apart. By studying 100 isotopes ...

For the first time, it has been possible to use a laser to transfer an atomic nucleus into a state of higher energy and then precisely track its return to its original state. This makes it ...
