Abstract
High-spin states in and have been populated with Coulomb excitation at beam energies slightly above the Coulomb barrier. In each nucleus a new side band has been identified in γ-γ coincidence measurements and has been interpreted as the lowest-lying octupole excitation. The alignments and Routhians of these bands, as well as the branching ratios of decays to the ground-state bands, are in good agreement with results from cranked RPA calculations.
