Abstract

Hard-core final state interaction effects in the response function are investigated in the asymptotic limit of momentum transfer q->Infinity. A new treatment of the response is presented, which displays the relevant scattering contribution. A modification of the otherwise expected free response is obtained for Fermi and Bose systems and smearing of the condensate peak is shown in this limit. A comparison with other treatments of final state interactions is made.
