Elektronütközéses

Elektronütközéses refers to the phenomenon of electron-electron scattering. This is a fundamental interaction in physics where two electrons collide and exchange energy and momentum. While electrons are elementary particles and do not possess internal structure in the way composite particles do, their interaction is governed by the electromagnetic force, mediated by photons.

In classical physics, collisions often involve a direct transfer of kinetic energy. However, electron-electron scattering is a quantum mechanical process. The interaction is characterized by the Coulomb force between the negatively charged electrons. When two electrons approach each other, their wave functions overlap, leading to a probabilistic scattering event. This process is crucial in understanding the behavior of charged particles in various environments, from plasmas to semiconductors.

The probability and outcome of an electron-electron collision depend on factors such as the initial energies and trajectories of the electrons. Theoretical frameworks like Quantum Electrodynamics (QED) provide precise calculations for these interactions. Electron-electron scattering plays a role in phenomena such as bremsstrahlung radiation, where an electron loses energy by emitting a photon during a collision, and in the collective behavior of electron gases in solid-state physics. It is a key process for energy thermalization and momentum redistribution within a system of electrons.
