Adapted Gaussian basis sets for atoms from Li through Xe generated with the generator coordinate Hartree-Fock method

The generator coordinate Hartree-Fock method is used to generate adapted Gaussian basis sets for the atoms from Li (Z=3) through Xe (Z=54). In this method the Griffin-Hill-Wheeler-Hartree-Fock equations are integrated through the integral discretization technique. The wave functions generated in thi...
