A method is proposed for determining the ground state of the Hamiltonian H=ΣkεkNk-ΣijklVijklaiajakal

when the residual interaction is such that aiajakal=NiNj(1-Nk)(1-Nl)12NkNl(1-Ni)(1-Nj)12

is a good approximation. The method is applied to pairing interactions involving one type of nucleon as well as to the generalized pairing problem containing neutron-neutron, neutron-proton, and proton-proton interactions.
