The total energy per atom of the lithium metal has been calculated as a function of the internuclear distance with several versions of the alternant molecular orbital method (AMO). This method is applicable to alternant systems like the body-centered cubic lattice of the alkali metals. The purpose of the method is to allow electrons with different spins to occupy different orbitals in order to account at least partially for correlation.
