Description
High-spin states have been studied in 59135Pr, populated through the 116Cd(23Na,4n) reaction at 115 MeV, using the Gammasphere γ-ray spectrometer. The negative-parity yrast band has been significantly extended to spin ∼45(ℎ/2π) and excitation energy 21.5 MeV, showing evidence for several rotational alignments. The positive-parity yrast band of 58134Ce, populated through the p4n channel of this reaction, was also populated to spin ∼38(ℎ/2π) and excitation energy 18 MeV. Cranking calculations indicate that these nuclei are soft with respect to the triaxiality parameter γ and that several competing nuclear shapes occur at high spin.
