Abstract
The total energy of the uniform electron gas is calculated in the alternant molecular orbital (AMO) approximation for a cubic Fermi surface. This energy is lower than the restricted Hartree-Fock energy for the cubic Fermi surface for rs>or=9.27 au. This transition point is discussed from the point of view of Adams' instability criterion.Keywords
