Response functions for inelastic electron scattering from 58Ni have been determined for momentum transfers of q ≈ 0.4-2 fm-1. A multipole decomposition of the full continuum for excitation energies below 35 MeV yields new features of the E1 and E3 strengths. The E2 strength is in excellent agreement with α-scattering data which demonstrates the usefulness of both probes and shows the isospin purity of the isoscalar giant quadrupole resonance.
