NationMaster - Encyclopedia: Stark effect

The Stark effect is the splitting of a spectral line into several components in the presence of an electric field. This splitting is called a Stark Shift. It is analogous to the Zeeman effect where a spectral line is split into several components in the presence of a magnetic field.

Discovered by Johannes Stark.

Stark effect (137 words)
	The broadening or splitting of a spectral line that results when an electric field slightly changes the energy levels of a radiating atom or ion.
	Stark broadening is proportional to the ion and electron density in a plasma and is therefore a good indicator of pressure in a stellar atmosphere and hence of the star's luminosity.
	The effect is named after the German physicist Johannes Stark (1874-1957).
