Proton-neutron and proton-proton correlations in medium-weight nuclei and the role of the tensor force.
A detailed analysis of the effect of short-range and tensor correlations on one- and two-nucleon momentum distributions of medium-weight nuclei (12<or=A<or=40) is carried out. Although our Letter is primarily aimed at understanding the role of the tensor force on nucleon momentum distributions of medium-weight nuclei, the possible relevance of our results for the interpretation of (e, e'N) and (e, e'2N) processes at high Q2, aimed at investigating nucleon-nucleon correlations, is discussed.
