The diagonalization approximation is used to investigate the resonance states of He and H- respectively near the n = 4 and n = 5 hydrogen thresholds. Computations are carried out for states of symmetries; energies, total and partial widths of autoionization states of helium and autodetaching states of the negative hydrogen ion are calculated. Comparison is made with experiment and theory.
