PLASMA AND LIQUID-METAL RESISTIVITY CALCULATIONS USING THE ZIMAN THEORY

Liquid-metal and dense plasma resistivities are calculated for some tr ansition metals and for Al using the Ziman theory together with the se lf-consistent average atom INFERNO code. The hypernetted-chain equatio n is used for calculating the structure factors when no experimental d ata are available. Attempts are made to improve upon previous calculat ions by including more accurate electron densities of states as well a s the second and third order terms in the multiple scattering expansio n of the T matrix. Calculated resistivities with the exception of low density Cu plasma are up to a factor of 4 higher than the experiment f or transition metals and between three to four times smaller for Al li quid metal and plasma. The results of the model used in this paper do not seem to agree with the recent experimental data for Cu at a densit y of the order of a gram and temperatures of several eV as recently ob tained by DeSilva and Kunze [Phys. Rev. E 49, 4448 (1994)].
