    "abstract": "A generalized RPA formalism is presented which treats pp and ph correlations\non an equal footing. The effect of these correlations on the single-particle\nGreen function is discussed and it is demonstrated that a self-consistent\ntreatment of the single-particle Green function is required to obtain stable\nsolutions. A simple approximation scheme is presented which incorporates for\nthis self-consistency requirement and conserves the number of particles.\nResults of numerical calculations are given for $^{16}$O using a G-matrix\ninteraction derived from a realistic One-Boson-Exchange potential.",
