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 ...

Somewhere beyond the Milky Way, a natural accelerator is flinging subatomic shrapnel toward Earth at energies that dwarf ...

Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying nuclear decay modes is crucial for understanding properties of atomic ...

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.

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 ...

Scientists have demonstrated a new way to use high-energy particle smashups at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy (DOE) Office of Science user facility for nuclear ...

For the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new ...

The University of Liverpool has signed a Memorandum of Understanding (MoU) with Mirion Technologies to expand collaboration in nuclear science, radiation protection and related strategic technologies.

Delve into the detail of atomic physics. As the basic units of matter, atoms are the building blocks for everything in the universe. Once thought to be indivisible, we now know they can indeed be ...
