N2 - A study of the influence of the chemoionization processes on nonstationary gas-discharge conductivity has been performed. Due to energetic, suprathermal electrons, which appear in the chemoionization reactions, the highly nonequilibrium and time dependent nonlocal electron distribution function is formed. In such gas-discharge plasma, thermal electrons always have positive conductivity, while suprathermal, energetic electrons may have negative conductivity in heavy (argon, krypton, and xenon) noble gases dependent on conditions, which may lead to the nonmonotonic temporal behavior of gas-discharge plasma conductivity and potentially may create the absolute negative conductivity.
