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.

To study the inner workings of an atom's nucleus, scientists have traditionally relied on sophisticated particle colliders to ...

MIT researchers have devised a new molecular technique that lets electrons probe inside atomic nuclei, replacing massive particle accelerators with a tabletop setup. By studying radium monofluoride, ...

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 ...

MIT scientists used radium monofluoride atom to observe electrons entering atomic nuclei, revealing new details of nuclear magnetism.

The pulse of an atom's magnetic heart as it ticks back and forth between quantum states has been timed in a laboratory. Physicists used a scanning tunneling microscope to observe electrons as they ...

Quantum mechanics explains why the electrons can keep spinning indefinitely. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. An atom is best ...

"Developed initially for space observations, the Compton Camera has now proven its worth as a tool for addressing complex scientific questions in other domains as well." When you purchase through ...

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 ...
