STRUCTURE FUNCTIONS OF NUCLEI FOR ALL X AND Q(2)

We propose a modified version of the quark cluster model to describe t he structure functions of nuclei over the complete kinematical region of the variables x = Q(2)/2m(N) nu and Q(2). The model accounts for sh adowing effects at very small x and anti-shadowing in the region 0.1 l ess than or equal to x less than or equal to 0.3. The experimental obs ervation that the ra tio of structure functions F-2(A)/F-2(D) is less than unity in the region x similar or equal to 0.5 is related to the i nfluence of multiquark clusters. The model agrees with all available d ata on nuclear structure fuctions for a large variety of nuclei, and c an be used to make predictions for kinematical regions not yet studied experimentally.
