ACCURATE UNIVERSAL GAUSSIAN-BASIS SET FOR ALL ATOMS OF THE PERIODIC-TABLE

We have applied a discretized version of the generator coordinate Hart ree-Fock method to generate a universal Gaussian basis set for the ato ms from H through Lr. In general, for He to Rn the ground state Hartre e-Fock total energy results obtained with our universal Gaussian basis set are lower than the corresponding ones obtained by Clementi et al. using larger atom-optimized geometrical Gaussian basis sets. For the atoms from H through Lr we have obtained ground state energy values wi th at least seven digits of accuracy (except for Pm, with six digits), in comparison with the corresponding ten digits of the numerical Hart ree-Fock total energy results.
