The lines emitted with radiative decay of doubly excited states near the resonance transitions of heliumlike ions are convenient for spectroscopic diagnostic plasma because of the fact that the satellite and the resonance line lie in a narrow spectral interval and therefore wavelength calibration of the spectrometer is unnecessary. In this paper the transitions from autoionized levels in a three-electron beryllium ion were employed for the diagnostics of the plasma of an impulsive discharge in a vacuum. The spectrum of dielectronic satellites was excited in the discharge between beryllium electrons. The line intensities were determined photographically. Atomic model calculations of configuration interaction and electron temperature along with effective charge and electric conductivity are presented.
