Quasielastic Electron Scattering on 65Cu

The pioneer method for extraction of quasielastic part from the spectrum of scattered electrons is proposed. The essence of the method is in simultaneous multipole analysis of the mix of quasielastic and resonant formfactors. The identification of resonant peaks and quasielastic part of the formfactor have been held not in scattered electron spectra but in the transition probability energy dependence of each multipolarity where there difference between resonant and quasielastic processes is clear. The pure quasielastic spectrum for 65Cu with the electron energy E0 = 225 MeV and scattered angle θ = 650 was obtained as a result of the application of this method
