    Abstract

    New band structures have been observed in 112Pd, 113Pd, 115Pd and 118Pd produced via the fusion-fission reaction 12C+238U at a bombarding energy of 90 MeV. γ-γ-γ coincidence measurements have been performed with the Euroball III array. The first crossings observed in even-mass palladium up to A=118 are interpreted as the alignment of a vh11/2 pair. This interpretation is supported by the rotational behavior of odd-mass palladium. Hartree-Fock-Bogoliubov calculations using D1S-Gogny force suggest a similar interpretation consistent with a prolate deformation.
