An attempt hasbeen made for the resolution of opposing charged layer structures in DL. Excitation processes in theconstriction region are studied. Using the linearization method for the nonstationary balance equationssystem and choosing appropriate discharge conditions, the step excitation rate by the electron impact for6 3 P 2 →7 1 S 0 transition in Hg is determined.
