Abstract
The level structures of odd A similar to 110 Ru, Pd, and Cd isotopes have b een investigated following the fission of compound nuclei formed in heavy-i on fusion reactions. New sequences have been assigned to Ru-107, and to Cd- 113,Cd-115,Cd-117,Cd-119 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 sequence s as originating from the neutron h(11/2) orbital. The occupation of this o rbital polarizes the nucleus to a nonaxial shape in odd-A Ru, Pd and Cd iso topes over a wide range of neutron numbers. The yrast bands in the Cd-114,C d-116,Cd-118,Cd-120 cores have been extended to higher spins and excitation energies.
