C. Hartwigsen et al., RELATIVISTIC SEPARABLE DUAL-SPACE GAUSSIAN PSEUDOPOTENTIALS FROM H TORN, Physical review. B, Condensed matter, 58(7), 1998, pp. 3641-3662
We generalize the concept of separable dual-space Gaussian pseudopoten
tials to the relativistic case. This allows us to construct this type
of pseudopotential for the whole Periodic Table, and we present a comp
lete table of pseudopotential parameters for all the elements from H t
o Rn. The relativistic version of this pseudopotential retains all the
advantages of its nonrelativistic version. It is separable by constru
ction, it is optimal for integration on a real-space grid, it is highl
y accurate, and, dye to its analytic form, it can be specified by a ve
ry small number of parameters. The accuracy of the pseudopotential is
illustrated by an extensive series of molecular calculations.
