## Abstract We introduce here a new partitioning of the Hamiltonian in calculating pairβcorrelation energies using manyβbody perturbation theory, by which we are able to eliminate the offβdiagonal particleβhole (__p__β__h__) ladders exactly to all orders in the perturbation expansion. In this formu
