A method is proposed for determining the ground state of the Hamiltonian
when the residual interaction is such that
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.
