N2 - The folded-diagram procedure of Brandow, suitable for many-body perturbation-theory calculations when unperturbed functions are degenerate, is applied to the four lowest excited + states of H2 at R=1.4 bohr. Calculating energies up to third order (inclusive) and estimating higher-order corrections, an agreement of 1 kcal/mole is obtained with the accurate results of Kolos and Wolniewicz.
