Abstract：
High-spin states in ¹³⁹Nd nucleus have been reinvestigated with the reaction ¹²⁸Te (¹⁶O, 5n) at a beam energy of 90 MeV. The level scheme has been expanded with spin up to 47/2 h. At the low spin states, the yrast collective structure built on the νh_{11 / 2}^－1 multiplet shows a transitional shape with γ≈32° according to calculations of the triaxial rotor-plus-particle model. Three collective oblate bands with γ~－60° at the high spin states were identified for the first time. A band crossing is observed around hω~0.4 MeV in one oblate band based on the 25/2^－ level.
