A simulation by US theoretical physicists has provided the first fully microscopic characterization of the moment an atom ...

The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and one electron in the region outside the nucleus. The electron and proton are attracted to each other.

Nuclear fission has powered our world and medical advancements for decades. What exactly happens when an atom's nucleus splits into two parts?

Physicists have made a breakthrough in the development of a nuclear clock, a new kind of ultraprecise clock that could ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

A pair of physicists from MIT and Jefferson Lab and an animator have created a new visualization of the atomic nucleaus. For ...

Based on an experiment at CERN, a collaboration led by the Niels Bohr Institute, University of Copenhagen, can predict hitherto unchartered changes in the shape of nuclei.

At low energies, the nucleus of an atom appears to behave as if it were made of protons and neutrons, but when the energies are higher, the influence of quarks and gluons becomes "visible" to the ...

Why are there atomic clocks but no nuclear clocks? After all, an atom's nucleus is typically surrounded by many electrons, so ...

The nuclei of different atom species have different shapes from round to oval ... to about 5 trillion degrees Celsius (°C), whereby the components of the nucleus c– protons and neutrons – are broken ...

If we figure out how to harness this effectively and efficiently, this is it. This is the end. This is the solution,” an expert tells us.

Two dark matter experiments have spotted signs of neutrinos knocking into atomic nuclei in their detectors. The finding portends a future obstacle for the ...
