Optical investigations of turbulent electrostatic oscillations produced when a plasma stream interacts with a partially-ionized gas

We determined the turbulent electric fields produced when an ion stream interacts with a plasma, by measuring the intensities of the forbidden lines of neutral helium and the Stark broadening of the hydrogen-atom lines.
