ResumoWe elaborate a theoretical approach to the dynamics of nuclear transparency in hard nuclear reactions, based on the hadronic eigenstate expansions of the nucleon state produced in the hard scattering. Transparency occurs at values of transfer momentum larger than q ∼ 10 GeV. The role of the Fermi motion of the struck nucleon is found to be crucial.
