Abstract

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.
