In the present paper axial distributions of plasma and floating potentials, electron and ion densities and EEOP have been measured in the OL region of a Hg discharge constriction. An attempt has been made for the resolution of opposing charged layer structures in OL. Excitation processes in the constriction region are studied. Using the linearization method for the nonstationary balance equations system and choosing appropriate discharge conditions, the step excitation rate by the electron impact for 6 3 P 2 ~7 1S 0 transition in Hg is determined.
