Manifestation of ground-state correlation in momentum distribution and response function

A relation is studied between the momentum distribution and the response function of nuclei in the quasielastic region. It is shown that a consistent treatment of the ground-state correlation leads simultaneously to (i) the existence of the high-momentum tail of the momentum distribution and to (ii) a quenching of the response function around the quasielastic peak region and an enhancement of the high-energy tail part, i.e. they are two different manifestations of the ground-state correlation.
