noun
bremsstrahlung; braking radiation
Technical physics term for electromagnetic radiation produced when a charged particle, especially an electron, is decelerated by the electric field of an atomic nucleus. Also known as braking radiation. Cross-referenced with 制動放射, which is a synonym.

X線管では、高速電子がターゲットに衝突して制動輻射が発生する。
In an X-ray tube, bremsstrahlung is produced when high-speed electrons hit the target.
制動輻射は、電子が原子核の近くを通過するときに強く放出される。
Bremsstrahlung is strongly emitted when an electron passes close to an atomic nucleus.
Synonym for 制動輻射. Both mean bremsstrahlung, but 制動放射 uses the more common character 放 (release) instead of 輻 (spoke/radiation). 制動放射 is likely more frequent in modern texts.
The term is a direct calque from German 'Bremsstrahlung' (braking radiation). 制動 (braking) + 輻射 (radiation). The character 輻 originally means 'spokes of a wheel', but here it is used in the sense of 'radiating' as in 輻射 (radiation).
