Covalent bonds, in which two atoms are bound together by sharing a pair of electrons, form the scaffolding that underpins the majority of organic compounds. In 1931, the Nobel Laureate Linus Pauling ...

Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Electron capture processes in ion–atom collisions constitute a critical phenomenon in understanding the interplay between charged particles and neutral atoms. In these collisions, an ion may capture ...

Charge exchange is a fundamental process whereby a highly charged ion captures one or more electrons from a neutral species, leading to the emission of X‑rays. This electron capture event is central ...
