Abstract Cross sections for elastic magnetic electron scattering from65Cu and63Cu have been obtained at momentum transfers 0.4≦q≦0.9 fm−1. They are interpreted in terms of the shell model with the inclusion of core-polarization and meson-exchange effects. Within this framework the magnetic octupole moment is extracted from the data. In contrast to shell-model calculations with a closed56Ni-core this approach gives a fair description of both the magnetic dipole moment and the magnetic form-factor data. However, the same calculation fails to reproduce the strong enhancement of the quadrupole moment. At present, it is not yet understood what is exactly missing in the theory to give the proper description of both the quadrupole moment and the magnetic octupole moment.
