Abstract

The level structures of odd [Formula Presented] Ru, Pd, and Cd isotopes have been investigated following the fission of compound nuclei formed in heavy-ion fusion reactions. New sequences have been assigned to [Formula Presented] and to [Formula Presented] isotopes using the complementary fission fragment technique. A comparison with neighboring neutron-deficient and neutron-rich odd-A Ru, Pd, and Cd isotopes supports an interpretation of these sequences as originating from the neutron [Formula Presented] orbital. The occupation of this orbital polarizes the nucleus to a nonaxial shape in odd-A Ru, Pd and Cd isotopes over a wide range of neutron numbers. The yrast bands in the [Formula Presented] cores have been extended to higher spins and excitation energies.
