Abstract
Using the Green' s function method, the effect of the error in the calculated normalization for the band wave function on the results of self-consistent calculations is investigated. The sensitivity of self-consistently calculated conduction-band parameters to the approximate estimation of the normalized integral is shown to be slight. The investigati on is carried out for metallic lithium in the approximation of a frozen atomic core. The exchange potential is chosen according to Kon and Shen.
