A change of direction of an Electron through interaction with matter. It can redistribute a transmitted beam outside a detector's collection region without stopping every diverted Electron.
The quantum lifetime determines the broadening of a single-particle spectral level by scattering. It need not equal the momentum relaxation time: small-angle scattering broadens levels while relaxing current weakly. A common Lorentzian broadening convention is a half-width .

Electron scattering is a process in which electrons are directed towards a target material, and their trajectories are altered as a result of interactions with the target’s atoms, nuclei, or electrons. This phenomenon is fundamental in various fields of physics and has important applications in understanding atomic structure, particle physics, and materials science. **Key Concepts:** 1. **Types of Scattering:** - **Elastic Scattering:** The kinetic energy of the electrons is conserved, although their direction may change.
