dc.descriptionWe study normalization problems associated with use of perturbatively correlated groundstates in extended RPA schemes in the context of a specific but typical example. The sensitivity of the results to the amount of 2p2h admixtures to the correlated ground state is also investigated in terms of a modification of the standard perturbative approach.
