Abstract

Consideration is given to the chief spectroscopic methods of measuring electric fields in plasma media. These methods are based on the effects of Stark splitting of spectral lines of hydrogen atoms, and the appearance of forbidden (by parity) components in the emission spectra of helium atoms. An analysis is made of methods of measuring weak electric fields (with intensities from 10 to 100 V/cm) in plasma. The methods are based on the appearance of forbidden components in the spectra of laser-induced fluorescence of diatomic polar molecules and the Stark effect of Rydberg atoms.
