โฆ Synopsis
The effectiveness of well-tempered Gaussian basis sets has been tested for the atoms He-Ar, Ag, and Xe, It has been found that orbital exponents optimized through the well-tempered scheme for non-relativistic atoms can be carried over to relativistic calculations to produce wavefunctions close to the relativistic Hartree-Fock limit.

Dirac-Fock-Roothaan calculations have been performed using various sizes of contractions of Gaussian basis sets for iodine (Z= 53 ) and gold (Z= 79). The results show that contractions of large exponent bases of s and p symmetry species have large effects on the total energies and the orbital energi
## Abstract Relativistic singleโfamily exponent Gaussian basis sets for molecular calculations are presented for the 80 atoms ~1~H through ~80~Hg. The exponent parameters shared by Gaussian basis functions of all symmetry species are fully optimized. Two nucleus models of uniformly charged sphere a
It is pointed out that my arguments on the effects of contractions of the relativistic basis sets on the total energies are made in the sense of the absolute magnitude while Ishikawa's are made in the sense of the relative magnitude. Hence they do not contradict each other.
