The connection is established between the intensity distributions of the spectral lines along a negative glow discharge column and the individual elementary processes which take place in a low-temperature nonequilibrium plasma (direct electron excitation, step processes, recombination, collisions of the second kind, and charge exchange). The experiments were made in pure inert gases and mixtures of them at pressures 1-30 mm Hg and discharge current densities of 10-2-10+1 mA/cm2. Knowledge of the intensity distributions together with some additional data (such as the electron density, the energy distribution function of the electrons, and the population of the levels) makes it possible to estimate more accurately the rates and cross sections of the reactions which lead to excitation of the glow discharge.
