The spectral function for finite nuclei is computed within the framework of the local-density approximation, starting from nuclear matter spectral functions obtained with a realistic nucleon-nucleon interaction. The spectral function is decomposed into a single-particle part and a ‘‘correlated’’ part; the latter is treated in the local-density approximation. As an application momentum distributions, quasiparticle strengths and overlap functions for valence hole states, and the light-cone momentum distribution in finite nuclei are computed.
