Electrical Conductivity of Partially Ionized Na‐Cs Plasma Mixtures

The electrical conductivity of partially ionized sodium‐cesium plasmas is calculated starting from the electron kinetic equation taking into account the electron‐electron, electron‐ion and the elastic electron‐atom scattering. The transport cross sections follow from the scattering phase shifts solving the corresponding Schrödinger's equation with effective interaction potentials. In order to calculate the plasma composition a coupled law of mass action is used. The electrical conductivity of the plasma mixture is then discussed for densities 1016…1021cm−3and for temperatures 3000 K… 10000 K.
