Abstract
The x-ray incoherent cross section has been measured in crystalline LiF. The static structure factor and the exchange and correlation energy of valence electrons in LiF have been obtained. Making use of the results of a recent Hartree-Fock calculation in solid LiF, the correlation contribution to the ground-state energy has been determined. The static structure factor data have been analyzed to deduce the valence-electron pair-correlation function. Comparisons have been carried out with the recent quantum Monte Carlo calculations in the homogeneous interacting electron gas.File in questo prodotto:
