elektronitörmäyksen

Elektronitörmäys, also known as electron scattering, is a fundamental process in physics where an electron interacts with another particle, typically another electron or an atom. This interaction results in a change in the momentum and energy of the colliding particles. Electron scattering is a crucial tool for probing the structure of matter and understanding fundamental forces.

In the context of atomic physics, electron scattering off atoms is used to study the electronic structure and energy levels of the atom. By analyzing the scattered electrons, scientists can deduce information about the electron cloud and the orbitals within the atom. This technique has been instrumental in validating quantum mechanics and discovering new atomic properties.

Electron-electron scattering, a specific type of electron scattering, is a key process in high-energy physics. It allows for the study of the electromagnetic force and the fundamental properties of electrons. Experiments involving electron-electron collisions at particle accelerators provide insights into quantum electrodynamics (QED), one of the most precisely tested theories in physics. The principles of electron scattering are also relevant in fields such as materials science, where it can be used for characterization techniques like electron microscopy and diffraction.
