A MODEL STUDY OF NUCLEAR-STRUCTURE FUNCTIONS

We calculate the structure function for a deuteron using the hadronic quark cluster decomposition. By assuming that nuclei might be composed of quasi deuterons, we study their structure functions. The procedure enables a quantum mechanical parametrization of various scenarios, am ong them nuclear dynamics and nucleon swelling. Moreover it is special ly suited to study quark exchange effects. We show, within a scheme wh ere perturbative evolution effects are minimized, that the region arou nd x = 1 is very sensitive to these two mechanisms and their effects c an be disentangled.
