✦ Synopsis
We have applied a discretized version of the generator coordinate Hartree᎐Fock method to generate adapted Gaussian basis sets for atoms Cs Ž . Ž . Zs55 to Lr Z s 103 . Our Hartree᎐Fock total energy results, for all atoms studied, are better than the corresponding Hartree᎐Fock energy results attained with previous Gaussian basis sets. For the atoms Cs to Lr we have obtained an energy value within the accuracy of 10 y4 to 10 y3 hartree when compared with the corresponding numerical Hartree᎐Fock total energy results.

The generator coordinate Hartree᎐Fock GCHF method is employed as a criterion for the selection of a 18 s12 p Gaussian basis for the atoms Na᎐Ar. The role of the weight functions in the assessment of the numerical integration range of the GCHF Ž . equations is shown. The extended basis is then contra
Accurate Gaussian basis sets (18s for Li and Be and 20s11p for the atoms from B to Ne) for the first-row atoms, generated with an improved generator coordinate Hartree-Fock method, were contracted and enriched with polarization functions. These basis sets were tested for B 2 , C 2 , BeO, CN -, LiF,
