Properties of low-lying states inCe142via high resolution electron scattering

Abstract
Differential cross sections for inelastic scattering from Ce142 have been measured for excitation energies less than 3.3 MeV over a range of momentum transfer of 0.4 to 2.5 fm1. The data have been analyzed to extract transition charge densities. These densities are interpreted in terms of a quasiparticle-phonon approach and finite Fermi system theory to disentangle the collective and noncollective modes of excitation.
