Different atoms and ions possess characteristic energy levels. Like a fingerprint, they are unique for each species. Among ...

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 ...

Where does the periodic table of chemical elements end and which processes lead to the existence of heavy elements? An international research team reports on experiments performed at the GSI/FAIR ...

Nucleons, comprising protons and neutrons, are not elementary particles but are built from quarks and gluons held together by the strong nuclear force. At typical inter-nucleon distances, effective ...

Asteroid impacts with global consequences are vastly rarer, especially compared to the frequency with which they appear in ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense ...
