1944 W. 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.
1948 N. F. Mott & I. N. 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.
1958 New Scientist 16 Jan. 14/1 A radiative heat loss due to this process (technically known as bremsstrahlung radiation).
1962 Newnes Conc. Encycl. Nucl. Energy 90/2 Bremsstrahlung..The name (braking radiation) originates in the radiation produced when electrons are stopped in an absorber.
1965 New 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.
