摘要：

Emissive properties of cold cathodes under the conditions of abnormal glow discharges are considered. Unlike the earlier made investigations, account is taken of alloying the surface layer by fast atoms generated in the cathode fall region. Atom implantation into the cathode to a depth of 10 nm changes the electron emission in a gas discharge radically as compared with vacuum conditions. Potential emission is reduced because of an increase in the surface work function. Kinetic emission is enhanced owing to an increase of the inelastic energy losses by fast atoms in the cathode material. Also greatly amplified is photoemission; moreover, its mechanism is changed.
