Table 1:
Static lattice properties of LaF3 determined using the
interionic potential described in the text. The experimental lattice
parameters are from K. Schlyter, Arkiv. Kemi. 5, 73 (1952) and the
experimental elastic constants are from R. Laiho, M. Lakkisto and T. Levola,
Phil. Mag. A47, 235 (1983).
