bremsstrahlung Nuclear Physics.|ˈbrɛmsʃtrɑːlʊŋ|
[G., lit. ‘braking radiation’, f. bremsen to brake + strahlung radiation.]
The electromagnetic radiation produced by the retardation of a charged particle, usu. an electron passing through the field of a nucleus.
1944W. Heitler Quantum Theory Radiation (ed. 2) iii. 160 This is..the case for the Bremsstrahlung (continuous X-ray emission). The Bremsstrahlung is one of the most important processes affecting the penetrating power of high-energy electrons by passing through matter. 1948Mott & Sneddon Wave Mech. x. 275 Among [radiation] processes of the third order the most important is ‘Bremsstrahlung’—the emission of radiation by an electron passing through the field of a nucleus. 1958New Scientist 16 Jan. 14/1 A radiative heat loss due to this process (technically known as bremsstrahlung radiation). 1962Newnes Conc. Encycl. Nucl. Energy 90/2 Bremsstrahlung..The name (braking radiation) originates in the radiation produced when electrons are stopped in an absorber. 1965New Scientist 30 Dec. 905/1 The third possibility is that the X-rays from the Crab are produced by bremsstrahlung or the braking of electrons in a hot gas cloud at a temperature of 10–100 million °K. |
