Subject	has definition	has synonym	is a kind of	is an instance of	has antonym
bremsstrahlung	Electromagnetic radiation given out by electrons interacting with the ions in an ionized gas.	free-free transition	emission		inverse bremsstrahlung
fluorescence	The emission of light at one wavelength, the green say, following absorption of light with a much shorter wavelength such as the ultraviolet. The UV photon parts with its energy by ejecting the electron into a high-energy level from which it cascades back down, releasing photons of lower energy and therefore longer wavelengths. A material which has this property is called a phosphor.	world point	emission
radiative recombination	See radiative capture.	world point	emission		ionization
recombination radiation	See radiative capture.	world point	emission
spontaneous emission	Radiation emitted by an isolated body.	world point		emission
stimulated emission	Radiation emitted by a body, such as an atom, when it is bombarded by radiation. The stimulated radiation has the same wavelength and direction as the bombarding radiation.	induced emission		emission
