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.
