Double-differential cross sections for the reaction Cu65(e, p0)Nig.s.64 were measured at eleven laboratory angles ranging from 42°to 138°with incident electron energies from 13 to 28 MeV. These have been decomposed into E1 and E2 components by use of a resonance model. Besides the large E1 cross section, the E2 strength is clearly separated at Ex=14.9 MeV with the width of 5.1 MeV corresponding to the isoscalar giant quadrupole resonance.
