This section discusses bremsstrahlung emission and the inverse absorption process (called inverse bremsstrahlung) in a macroscopic medium. We start with the equation of radiative transfer, which applies to general processes and not just bremsstrahlung: $${\displaystyle I_{\nu }(t,\mathbf {x} )}$$ is the radiation spectral … See more Bremsstrahlung /ˈbrɛmʃtrɑːləŋ/ , from bremsen "to brake" and Strahlung "radiation"; i.e., "braking radiation" or "deceleration radiation", is electromagnetic radiation produced by the deceleration of a charged particle … See more The full quantum-mechanical treatment of bremsstrahlung is very involved. The "vacuum case" of the interaction of one electron, one ion, and one photon, using the pure Coulomb potential, has an exact solution that was probably first published by A. Sommerfeld … See more Polarizational bremsstrahlung (sometimes referred to as "atomic bremsstrahlung") is the radiation emitted by the target's atomic electrons as the … See more The complete quantum mechanical description was first performed by Bethe and Heitler. They assumed plane waves for electrons which scatter at the nucleus of an atom, and derived a cross section which relates the complete geometry of that process to the … See more If quantum effects are negligible, an accelerating charged particle radiates power as described by the Larmor formula and its relativistic generalization. Total radiated power See more NOTE: this section currently gives formulas that apply in the Rayleigh–Jeans limit $${\displaystyle \hbar \omega \ll k_{\rm {B}}T_{e}}$$, … See more X-ray tube In an X-ray tube, electrons are accelerated in a vacuum by an electric field towards a piece of metal called the "target". X-rays are emitted as the … See more WebIn the matrix element for bremsstrahlung, the initial state of the electron must be represented by a plane wave plus an outgoing spherical wave, whereas the final …

WebBremsstrahlung is a very well-known physical phenomenon, used, for example, in any type of radiology equipment. When an electron or a beta particle passes through matter, it slows down, and a fraction of its energy is directly converted into X-rays.
