Nuclear structure of ^106Pd and ^106Cd from the (n,n^'γ) reaction
Abstract
Quadrupole shape vibrations are considered to be fundamental degrees of freedom of nuclei. Several candidates in the 48Cd and 46Pd region have been proposed as examples of good quadrupole shape vibrators; however, in recent studies of the heavy stable Cd nuclei, serious discrepancies from the vibrational decay pattern were found, suggesting a breakdown of the quadrupole vibrational picture. New studies of the 48Cd and 46Pd isotopes promise to bring new insights into the role of vibrations in nuclei. The low-lying states of ^106Pd and ^106Cd have been studied with the (n,n^'γ) reaction at the University of Kentucky 7-MV Van de Graaff accelerator facility. Gamma-ray excitation functions, angular distributions, and coincidence data (^106Pd) were used to characterize the excited states up to ∼4.0 MeV in each nucleus.
