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.

Physicists working with molybdenum-84, a nucleus containing exactly 42 protons and 42 neutrons, have found that this seemingly balanced atom defies one of nuclear physics’ longest-standing ...

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 ...

New research suggests a particle inside an atom can lose mass, offering a fresh look at how matter works at the smallest ...

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 ...

The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce ...

For the first time, physicists have developed a model that explains the origins of unusually stable magic nuclei based directly on the interactions between their protons and neutrons. Published in ...

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 ...
