Screening Effect of Degenerate Electron Background in High Density Plasmas. III. Local Field Correction Due to Electron Interaction

Abstract

Local-field correction due to the exchange and correlation effects between electrons introduces the screening function for the electron-ion interaction different from that for the ion-ion interaction. The resulting corrections to the calculation of the electric resistivity are numerically investigated. It is found that the corrections are substantial in magnitude even at the electron density (r_s\simeq1) of relatively weak coupling.
