We develop the Glauber theory description of initial- and final-state interactions (IFSI) in quasielastic A(p, 2p) scattering. We study the IFSI-distortion effects both for the inclusive and exclusive conditions. In inclusive reaction the important new effect is an interaction between the two sets of the trajectories which enter the calculation of IFSI-distorted one-body density matrix for inclusive (p, 2p) scattering and are connected with incoherent elastic rescat-terings of the initial and final protons on spectator nucleons. We demonstrate that IFSI-distortions of the missing momentum distribution are large over the whole range of missing momentum both for inclusive and exclusive reactions and affect in a crucial way the interpretation of the BNL data on (p, 2p) scattering. Our numerical results show that in the region of missing momentum p m ≲ 100–150 MeV/c the in-coherent IFSI increase nuclear transparency by 5–10%. The incoherent IFSI become dominant at p m ≳ 200 MeV/c.
