The processes of thermal and “cold” ionization for the calculation of the composition and conductivity of near-critical caesium vapours are considered. The degrees of thermal and “cold” ionization are calculated for the near-critical region, and the temperature and density regions with predominant role of the processes of “cold” ionization are indicated. The conductivity of caesium vapours is calculated as the sum of the conductivities of thermal electrons and jellium electrons. The obtained results agree with the experimental data on the gas branch of the binodal and the near-critical isotherms. These facts can serve as confirmation of the proposed hypothesis about the existence of the jellium in the gas–plasma region and its coexistence with thermally ionized electrons.

铯蒸气中的热电离和“冷”电离过程

考虑了用于计算近临界铯蒸气的成分和电导率的热和“冷”电离过程。计算了近临界区域的热电离度和“冷”电离度，并指出了“冷”电离过程起主要作用的温度和密度区域。铯蒸气的电导率计算为热电子和胶冻电子的电导率之和。得到的结果与双节点气体分支和近临界等温线的实验数据一致。这些事实可以证实关于气体-等离子体区域中果冻的存在及其与热电离电子共存的假设。
