Abstract: Recent BNL and Jlab data provided new evidence on two nucleon correlations2NC in nuclei. The data confirm the validity of the convolution model,describing the spectral function SF of a correlated pair moving in the meanfield with high and low relative and center-of-mass cm momenta, respectively.The model is built assuming that the wave function WF of a nucleus A,describing a configuration where the cm momentum of a correlated pair is lowand its relative momentum is high, factorizes into the product of the two-bodyWF and that of the A-2 system. Such a factorization has been shown to occur innuclear matter NM. Here it is shown that few-body systems exhibitfactorization, which seems to be therefore a general property, to be reproducedalso in studies of the WF of finite nuclei.
