Abstract
Thermal conductivity of the dense matter is calculated for the liquid metal state as well as for the crystalline lattice state. The calculation for the liquid metal state takes account of the best knowledge available on the structure factor of the ions in the high-temperature, classical limit and the dielectric screening due to degenerate electrons. The calculation for the crystalline lattice state takes account of the accurate form of the Debye-Waller factor. Key words: ATOMIC PROCESSES - DENSE MATTER
