Abstract: | An improvement in the computed structure of liquid lithium was obtained by adding the Xα Slater exchange energy to the electron pseudopotential of Ashcroft, Singwi, Sjölander et al. The remaining discrepancies can only be corrected by using a fully non-local pseudopotential for lithium, and perhaps by improving experimental accuracies of structure factors. |
