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 halflife of the HSI is longer than 2μs.From the systematic comparisons and the deformed independent particle model calculations for the N=83 isotones,the most possible particle configuration of π(1h²_11/2d_5/2)v(1i_13/21h_9/22f_7/2) and the spin-parity of J^π=27⁺ were assigned to this HSI corresponding to an oblate deformation with β=－0.18.
