Photoionization, the process by which an incident photon ejects an electron from an atom, lies at the heart of many atomic physics studies. Coupled with cross section measurements – which quantify the ...

Nuclear physics is the branch of science that examines the properties and behaviour of atomic nuclei, the densely packed assemblies of protons and neutrons held together by the strong interaction.

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 ...

The time is nigh for nuclear clocks. In a first, scientists have used a tabletop laser to bump an atomic nucleus into a higher energy state. It’s a feat that sets scientists on a path toward creating ...

The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The U.S. standard currently relies on ...

Nuclear Museum appoints world-renowned nuclear physicist and educator to Board of Trustees. I am excited to use my ...

Michael Riordan has spent decades ruminating on the history of physics, including events he participated in himself. The American Physical Society announced today that they will award physicist and ...
