The experimental and theoretical results of examination of a radiation spectrum for a pulsed discharge in vapour-gaseous intermixtures of a high-pressure helium are surveyed, with easily-ionizable impurities of vapour out of Fe/Al electrodes forming during a breakdown as the result of pulverization of electrodes. On the basis of model operation of experimental datas on the radiation spectrum of a near-electrode plasma, we have learnt a kinetics of population of exited states of atoms from vapours of a electrode methal, which derivate the Penning intermixture with a helium. The reference parameters of the explosive-emission centres are calculated on experimental data for delay times of forming the cathode sports and values of current densities in the near-electrode plasma. Investigated is an influence of electrode material vapour on the volumetric discharge stability at a qualitative level.
