We analyze second order contributions to the nuclear response function or polarization propagators, distinguishing self-energy like contributions from genuine 2p-2h states. Numerical evaluations of the various contributions are carried out, also suggesting techniques to cure the infinities.

Abstract
We analyze second order contributions to the nuclear response function or polarization propagators, distinguishing self-energy like contributions from genuine 2p-2h states. Numerical evaluations of the various contributions are carried out, also suggesting techniques to cure the infinities.
