A series of energy-minimized relativistic Gaussian basis sets for the eleme
nts with atomic numbers 19-118 is presented. The basis sets have been deriv
ed at the self-consistent field level as weighted average energies of the r
espective electronic configurations. A spherical Gaussian charge distributi
on has been used to model the nucleus. The basis sets are constructed as in
terleaving dual family sets with shared exponents within each family. The q
uality of the basis sets is better than double zeta.
