High-spin states in the odd-A ~(141)Pm nucleus

【摘要】：正Through the reaction ~(126)Te(~(19)F,4n) at a beam energy of 90 MeV,the high-spin states of ~(141)Pm have been investigated.The excited energy of previous level scheme has been updated from 5337.5 to 7353.1 Kev. Many new levels and transitions were identified in this work.Six collective bands in high spin states were newly established.One collective band was considered as decoupled band,and the possible configuration for the collective band was discussed.Two of the collective bands should be proposed as oblate bands,the others were oblate-triaxial bands.
