Ion Waves in a Weakly Ionized Plasma

抄録

The character of the propagation of ion waves in a weakly ionized plasma is studied experimentally. Ion waves are found to be waves of diffusion type, when the exciting frequency is lower than collision frequency between ions and neutral atoms, and otherwise, ion waves are acoustic waves. Form the waves of diffusion type, the diffusion coefficients are obtained, which are nearly equal to the values obtained by others.
