Popis:	The multipole {ital L}=2 structure function, measurable in deeply inelastic scattering of unpolarized leptons off a polarized {ital J}{ge}1 nuclear target, is a good indicator of exotic quark-gluon components in the nucleus. We present here estimates of this structure function for two different classes of nuclei--light nuclei describable in an independent-particle model approach and heavy nuclei described by slowly rotating collective variables. An estimate of the exotic effects is made within the context of a model wherein gluons and quarks from separate nucleons fuse together to alter the parton densities relative to that in isolated nucleons.
