Title: High-spin states and collective oblate bands in the odd-odd {sup 138}Pr nucleus

Abstract

High-spin states in the odd-odd {sup 138}Pr nucleus were reinvestigated with the reaction {sup 128}Te({sup 14}N,4n) at a beam energy of 64 MeV. Six collective bands were observed, and two of them were newly identified. For the {pi}h{sub 11/2}x{nu}h{sub 11/2} band, high-spin states are followed up to I{sup {pi}}=16{sup +}. The spin values for this band have been reassigned based on the systematical comparison with the neighboring nuclei. The observed band crossing is proposed to be due to the alignment of protons, and the signature inversion with the neutron number changing in La and Pr isotopes has been discussed. The other five collective bands are proposed to be based on oblate deformation with {gamma}{approx}-60 deg.
