## Abstract The generator coordinate method was implemented in the unrestricted Hartree‐Fock formalism. Weight functions were built from Gaussian generator functions for 1s, 2s, and 2p orbitals of carbon and oxygen atoms. These weight functions show a similar behavior to those found in the generato

## Abstract A polynomial version of the Generator Coordinate Dirac–Fock (p‐GCDF) method is introduced and applied to develop Adapted Gaussian Basis Sets (AGBS) for helium‐ and beryllium‐like atomic species (He, Ne^+8^, Ar^+16^, Sn^+48^, Be, Ne^+6^, Ar^+14^, and Sn^+46^) and for Kr and Xe atoms.

Generator coordinate Hartree-Fock calculations were performed for the fourteen-electron diatomic molecules Nz, CO and BF. The ground state HF energy and multipole electric moments were calculated. The Grifftn-Wheeler HF equations were solved by discretization with the aid of the HONDO program. The G
