✦ Synopsis

Using the method of superposition of correlated configurations, the contribution of linked correlation terms to the Li groundstate energy is calculated to be 14 bhartree. Consequently consideration of these terms lowered the upper bound from -7.478044 to -7.478058 hartree. This is the lowest upper bound for the Li ground state to date.

## Abstract Results are reported for multiconfiguration Hartree–Fock studies of correlation in the lithium ground state, which maintain orthogonality of orbitals within a configuration. It is shown that when the 1__s__‐ and 2__s__‐orbitals are fixed at their Hartree–Fock value, configurations for
