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

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 ...

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

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 ...

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 ...

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

this type of clock would register forces inside the atomic nucleus. "This would open up a whole range of research fields that could never be investigated with atomic clocks," adds Thirolf's ...

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 ...
