Vibrational states in108Pd studied by elastic and inelastic electron scattering

Abstract

The elastic electron-scattering form factor, and inelastic form factors for the 21+ (0.434 MeV), 22+ (0.931 MeV) and 3- (2.046 MeV) states in 108Pd were measured. The ground-state charge distribution parameters were obtained from a phase-shifted analysis of the elastic form factor. Analysis of the 21+ and 22+ form factors in the anharmonic vibrator model yields the reduced transition probabilities and the 21+ quadrupole moment (Qx, x=21+) which is in excellent agreement with recent Coulomb reorientation measurements. The 3- form factor is well described by the assumption that this state is a pure octupole vibration.
