line broadening
subject			fact

line broadening	changes property spectral line width
	has definition Increase in the range of wavelengths in which some characteristic emission or absorption occurs.
	is a kind of radiation modification
optical process	has domain optics

Kinds of line broadening :

• Doppler broadening (4 facts) - Line broadening caused by the thermal, turbulent, or mass motions of atoms along the line of sight.
• natural line broadening (2 facts) - Line broadening resulting from the fact that excited levels have certain mean lives, and these mean lives, by virtue of the uncertainty principle, imply a spread in the energy values.
• Paschen-Back effect (2 facts) - An effect on spectral lines obtained when the light source is located in a strong magnetic field, so that the magnetic splitting becomes greater than the multiplet splitting.
• pressure broadening (4 facts) - Line broadening caused by pressure.
• Stark effect (6 facts) - Line broadening due to the influence of electric fields.
• Zeeman effect (1 kind, 9 facts) - Line broadening due to the influence of magnetic fields.
