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 2μs. From the systematic comparisons and the deformed independent particle model calculations for the N = 83 isotones, the most possible particle configuration of π(1h211/22d5/2)ν(1i13/21h 9/22f7/2) and the spin-parity of Jπ = 27+ were assigned to this HSI corresponding to an oblate deformation with β= -0.18.
