In 2009 researchers found an "ionization surprise" that defied explanation. Until that time, it had been commonly thought that the ionization of atoms by strong laser fields was well-understood, but ...

Light interacting with hydrogen atoms enclosed in hollow cages composed of carbon atoms produces ionization. This phenomenon is particularly interesting because the light rays can have dramatic ...

To break free from an atom, the negatively charged electron typically has to absorb a high-energy photon, such as that from the ultraviolet (UV) or x-ray spectrum. The electron then gets excited ...

Researchers have for the first time measured the first ionization energy of lawrencium, the last of the actinides, validating predictions of the element’s electronic structure (Nature 2015, DOI: ...

In a step toward steering electrons inside molecules to control chemical reactivity, researchers report following electron-hole migration in iodoacetylene (H–C≡C–I) with 100-attosecond resolution ...

Mass spectrometry (MS) is already perhaps the most popular analytical chemistry tool in drug discovery and development. Its use is ubiquitous in bioanalytical laboratories for drug and metabolite ...

The best-laid plans of MICE and muons did not go awry: Physicists at the International Muon Ionization Cooling Experiment, or MICE, collaboration have achieved their yearslong goal of quickly sapping ...
