Though atomic nuclei are often depicted as static clusters of protons and neutrons (nucleons), the particles are actually ...

Physicists recorded the lowest-energy neutrino event yet, using signals from the particles’ antimatter counterpart produced ...

In atomic clocks, an atom’s electrons are pinged with electromagnetic radiation at specific frequencies. Bursts of energy excite the electrons, pushing them into a higher orbit around the atom.

A rather unassuming particle is playing an important role in the hunt for subatomic oddities. Similar to protons and neutrons ...

The researchers found that the neutrinos were at least 6.2 picometres, which is hundreds of times larger than the atomic nucleus. “It was a little bit surprising,” says Smolsky.

And making such sharp measurements within an atom’s nucleus might just give physicists access to vast, unexplored realms of the physical world. This “will really open a new window into looking ...

Formed from a cluster of protons and neutrons at the center of an atom, a nucleus is 10,000 times smaller than the atom as a whole, "like a fly in a cathedral," said David Jenkins, a nuclear ...

However, atomic clocks are also vulnerable to sync loss. Electromagnetic disturbances can disrupt excited electrons and affect the precision of the timekeeping, Zhang said.
