## Abstract A Brillouin‐Wigner perturbation expansion is derived for the generalized eigenvalue equation (__F__~0~ + __F__~1~)Ψ = μ__A__Ψ. The theory is applied through second order to calculate the ground‐state energies of the helium atom and the hydrogen molecular ion. The results are compared wi
