Calculation of energies of the isoelectronic series of atoms (Z ≤ 29) using the Hartree–Fock method

Abstract

Energy of atoms from hydrogen to cuprum and all their ions up to the one-electron atom that were calculated in the algebraic approximation of the Hartree–Fock method were compared with the experimental values obtained from ionization potentials. It was established that the calculated energies of atoms with Z ≤ 29 were only 0,3-1,0% greater than the experimental values. This indicated that the approximations underlying the Hartree–Fock method were correct.
