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 ...

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 ...

Physicists at MIT have developed a new way to probe inside an atom's nucleus, using the atom's own electrons as "messengers" within a molecule. Typically, experiments to probe the inside of atomic ...

The atom was not just a tiny particle. Inside it existed a force stronger than one could ever imagine.The atom was mostly empty space. At its center lies an extremely small "atomic nucleus." This fact ...

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.

A team of researchers successfully raised the energy state of an atom's nucleus with a laser, which could lead to new precision measurement technology with orders of magnitude higher accuracy than ...

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 ...
