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 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, ...

Physicists have studied a rare molecule to look at how magnetism is distributed within a radioactive nucleus for the first time. The rules of nature don’t, generally speaking, change. If you toss a ...
