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 ...

The study is part of Henna Kokkonen's doctoral thesis. Credit: Tommi Sassi For the first time in almost 30 years, the heaviest nucleus decaying via proton emission has been measured. The previous ...

A new atomic nucleus 149-Lutetium, consisting of 71 protons and 78 neutrons, has been synthesized. A new atomic nucleus 149-Lutetium, consisting of 71 protons and 78 neutrons, has been synthesized in ...

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 ...

For nearly 50 years, physicists have dreamed of the secrets they could unlock by raising the energy state of an atom's nucleus using a laser. The achievement would allow today's atomic clocks to be ...

(THE CONVERSATION) The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei – the center part of atoms, which make up all ...

A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable truth: We still don’t have a solid theoretical grasp of even the ...

Protons can hold an elementary particle heavier than themselves. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Protons may have more "charm" ...

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 ...

This video explores the fundamental components of an atom, including protons, neutrons, and electrons, challenging the ...
