Thomas-Fermi Sceening of Exchange Interactions
Exchange integrals for a screened Coulomb interaction of the Yukawa form with the Thomas-Fermi wave vector expressed in terms of the total electron density are calculated for transition metal, rare-earth and actinide atoms. The calculated exchange interactions are in remarkable agreement with those obtained from the local spin-density approximation.
