  The interplay between the orbital and spin currents in (e,e') excitations of
light nuclei is discussed. The microscopic analysis of E1 and M2 resonances was
performed within the particle-core coupling approximation (PCC) of the shell
model. The comparison of the theoretical results with the available
experimental data has shown that the studies of relative contributions of the
orbital and different spin components of the nuclear current into the
excitation of EJ and MJ resonances could be useful for the identification of
their configurational structure.
