The local density function approximation is used to construct a fundamental nonlocally soft pseudopotential for aluminum which satisfies the norm conservation condition. This pseudopotential is used to perform a self-consistent calculation of the aluminum electron energy spectrum, which proves to agree well with experimental data. The effect of various pseudopotentials (constructed with norm conservation) on the form of the energy spectrum is studied. It is shown that these various pseudopotentials lead to identical results.
