Abstract：
The high spin isomer (HSI) in ¹⁴⁴Pm was produced and separated by using the high spin isomer beam facility. Based on the measurements of γ-γ coincidence, γ-ray excitation functions, and isotropies, the decay level scheme of the HSI was established for the first time including 19 new high spin levels and 29 new γ-transitions assigned to ¹⁴⁴Pm by this work. The HSI-γ correlation measurement indicated that the half-life of the HSI is longer than 2 μs. From the systematic comparisons and the deformed independent particle model calculations for the N=83 isotopes, the most possible particle configuration of π(1h_11/2²d_5/2)υ(1i_13/21h_9/22f_7/2) and the spin-parity of J^*=27⁺ were assigned to this HSI corresponding to an oblate deformation with β=-0.18.
