Popis: Differential cross sections for electron scattering from {sup 140}Ce have been measured for excitation energies less than 3.3 MeV over a range of effective momentum transfer of 0.4 to 3.1 fm{sup {minus}1}. The data have been analyzed to extract transition charge densities. These densities are interpreted in terms of a quasiparticle-phonon model and self-consistent finite Fermi system theory to disentangle the collective and noncollective modes of excitation.
