The Influence of Exchange-Correlation Potential on the Total-Energy Calculations of Li, Na and K
Abstract
Total energy calculations are carried out on lithium, sodium and potassium for six different exchange-correlation formulas employing the linear muffin-tin orbital method (LMTO) within the atomic-sphere approximation (ASA). It is shown that in the determination of the stable crystal structure, (total energy - exchange energy) is a more reliable quantity than the total energy itself for these metals.
