This image depicts the radium atom’s pear-shaped nucleus of protons and neutrons in the center, surrounded by a cloud of electrons (yellow), and an electron (yellow ball with arrow) that has a ...

In a groundbreaking achievement, physicists have successfully peered inside the nucleus of a molecule using electrons as a ...

Since the atomic nucleus was first proposed in 1911, physicists simply assumed it was round. But are the nuclei of atoms really round? Intuitively this shape makes sense and physicists believed it ...

Researchers have been able to initiate a controlled movement in the very heart of an atom. They caused the atomic nucleus to interact with one of the electrons in the outermost shells of the atom.

For the first time, quarks and gluons were used to describe properties of atomic nuclei, which until now had been explained by the existence of protons and neutrons. The temporary pair of correlated ...

A novel experiment has revealed a phenomenon called the Bohr–Weisskopf effect in a pear-shaped nucleus in a molecule for the ...

Some atomic nuclei are thin-skinned — they’re surrounded by a slim shell of neutrons. Physicists now know how thick that neutron skin is for one particular type of nucleus. The skin of lead-208 — a ...

Scientists at Delft University of Technology have managed to watch a single atomic nucleus flip its magnetic state in real time. Using a scanning tunneling microscope, they indirectly read the nucleus ...

Physicists in Finland have created a pumpkin-shaped atomic nucleus that throws off protons in a rare kind of radioactive decay. The nucleus, lutetium-149, has the shortest half-life of any of a group ...
