bremsstrahlung (deceleration radiation, free-free transition)
subject			fact

bremsstrahlung	has antonym inverse bremsstrahlung
	has synonym deceleration radiation
	has synonym free-free transition
	has definition Radiation emitted or absorbed when a free electron is accelerated in the field of an atomic nucleus but remains in a hyperbolic orbit without being captured. Since bremsstrahlung is not quantized, photons of any wavelength can be emitted or absorbed. (Also called a free-free transition because the electron is free both before and after the transition.)
	has definition Electromagnetic radiation given out by electrons interacting with the ions in an ionized gas.
	is a kind of free-free transition
	is a kind of emission
emission	has inverse process absorption
atomic process	has domain atomic physics
radiation intensity modification	changes property intensity
event	has duration
	has time of occurrence

Kinds of bremsstrahlung :

• inner bremsstrahlung (2 facts) - The continuous electromagnetic radiation that accompanies the β-decay of nuclei.
• supra-thermal proton bremsstrahlung (2 facts) - Ordinary electron-proton bremsstrahlung viewed from the rest frame of the electron rather than the proton; in other words, the electron is at rest and the heavy particle (proton) is moving.
• thermal bremsstrahlung (2 facts) - A mode of X-ray production by very energetic electrons accelerated in the field of a positive ion.
