Results obtained from studying the properties of decaying plasmas are summarized. The measuring method consisted of measuring the number density of ion as well as the intensity of spectral lines and bands emitted by the plasma by mass spectrometer and light spectrometer techniques. The plasmas studied were produced in the rare gases, nitrogen, hydrogen and mixtures of these gases. The occurrence of various collision processes involving charged particles was established and the relevant reaction rate constants were determined. The production of charged particles by mutual collision between metastable particles was studied. Unknown processes resulting in the emission of nitrogen bands were found. Author
