摘要：

The high-spin states of 141Pm nucleus have been studied by using in-beam γ-ray spectroscopy technology through the 126Te( 19F, 4n) reaction at a beam energy of 90 MeV. The previous level scheme has been extended with spin up to 49/2 . Many new levels and transitions are identified. Five collective band structures are observed. Based on systematic comparison with the neighboring nuclei, two bands with strong I = 1 M1 transitions inside the bands are proposed as the oblate bands with γ～-60°, and three bands with large signature splitting have been suggested as the oblate-triaxial deformation with γ～-90 °. The characteristics for these bands have been discussed.
