Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

The ability to describe the internal structure of atoms is important not only for understanding the composition of matter, but also for designing new experiments to explore fundamental physics.

Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) have developed a novel method for investigating the internal structure of atoms and discovered ...

The Trump administration is planning to close a small, obscure laboratory whose work undergirds everything from microchip manufacturing to nuclear fusion. The Atomic Spectroscopy Group at the National ...
