We study spatial properties induced by pairing correlations, within the HFB approach employing the finite range D1S Gogny interaction. Local and non-local quantities, such as pairing tensor, are discussed as well as the coherence length. We show that a generic feature occurs at the surface of nuclei, namely Cooper pair of small size characterized by a coherence length xiapprox2 fm.
