The pressure, internal energy, and electronic transport coefficients of low-temperature Pb plasma were calculated at the temperatures 10–100 kK by means of an earlier developed model (E. M. Apfelbaum, Contrib. Plasma Phys. 2019, 59, e201800148). The plasma composition and thermodynamics were obtained using a chemical approach. The electronic transport coefficients were calculated within the relaxation time approximation with the new accurate momentum transfer cross-section electron-atom. The results of the present calculations have been compared with the new measurement data, obtained at relatively low densities, reaching 0.125 of the value in solid state, which corresponds to the area, where the model can be applied correctly. The good agreement between the calculations and measurements was obtained for both the pressure and the electrical conductivity.

低密度低温铅等离子体热物理性质的计算

通过早期开发的模型 (EM Apfelbaum, Contrib. Plasma Phys. 2019 , 59)在 10-100 kK 温度下计算了低温 Pb 等离子体的压力、内能和电子传输系数, e201800148)。等离子体成分和热力学是使用化学方法获得的。电子传输系数是在弛豫时间近似内用新的精确动量转移截面电子原子计算的。目前的计算结果与新的测量数据进行了比较，在相对较低的密度下获得了固态值的 0.125，这对应于可以正确应用模型的区域。对于压力和电导率，计算和测量之间获得了良好的一致性。
