Title: Observation of {nu}h{sub 11/2} sequences in odd A{approx}110 nuclei

Abstract

The level structures of odd A{approx}110 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 {sup 107}Ru, and to {sup 113,115,117,119}Cd 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 h{sub 11/2} 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 {sup 114,116,118,120}Cd cores have been extended to higher spins and excitation energies. (c) 2000 The American Physical Society.
