    Abstract

    Current models of nuclear structure describe nuclear states in terms of collective vibrations and rotations of a ground state. - One such quadrupole vibrational band is the gamma-band formed by vibrations of the short sides of a deformed nucleus. - When a nucleus that is in this mode decays to its ground state, the electromagnetic radiation is predicted to be entirely quadrupole in nature. - This prediction has been well documented in a wide range of nuclei. - However, a recent study of neutron rich molybdenum and ruthenium isotopes found a few gamma-band to ground-band transitions that contained almost no quadrupole radiation. - This work utilizes the Gammasphere detector array to examine the angular correlations in the de-excitations of the secondary fission fragments of 252Cf in order to make independent measurements of these results. - This work also uses the same technique to measure the multipole mixing ratios of gamma-band to ground-band transitions originating in states with spin-parity as high as 9+. - The results demonstrate that in these nuclei, electric quadrupole radiation is strongly favored in gamma to ground band transitions as has been predicted by theory.
