Electron impact

Electron impact refers to the process where high-energy electrons collide with atoms or molecules, transferring energy during the collision. This energy transfer can excite the atoms or molecules, raising them to higher energy states, or even ionize them by ejecting electrons. Electron impact is fundamental in various fields such as spectroscopy, plasma physics, and the operation of devices like cathode-ray tubes and electron microscopes. It helps scientists understand the structure and behavior of materials at the atomic level by observing how electrons interact with different substances.
