• The anode current-voltage characteristics of inert-gas-filled triodes have shown negative resistance at an anode potential at a range from one to several volts. With increasing gas pressure the negative characteristics becomes remarkable. Similar results are obtained in a dark plasma with a Langmuir probe. These phenomena are peculiar to heavy rare gases such as xenon, krypton and argon at higt pressure. These gases show the Ramsauer effect in the collision cross-section for the electron scattering. By consideration of this effect, the negative characteristics are explained. By using this negative resistance, experiments on oscillation and amplification are made and frequency dependence is examined. It is proposed that the intrinsic upper limit of frequency for this negative resistance is determined by the electron collision frequency and is more than 1000 Mc/s.
