“…The inclusion of octupole phonons into the shell model space has proven useful in the interpretation of high spin states in 4sEu [2] and might elucidate the origin of this state. The 10+ state at 1274 keV could then arise from the coupling [3 437 ], where the 7 state corresponds to the one at 515 keV.…”

Excited states of the Z = 61 isotopes Pm83 and Pm84 have been studied in the F + Te reaction at a beam energy of 85 MeV. Gamma-ray and conversion electron spectroscopy were used to establish the high spin states of Pm up to spin 20h and to extend the level spectrum of Pm up to a tentative spin of 2 h. Empirical shell model calculations in a configuration space truncated to the vr 1hiiy2, vr 1g~&'2, and vr 2d5&~p rotons and the v 2f7y2 neutron outside the ' Gd core reproduce the observed energy levels in good agreement with the experimental results. (nhiig2) configurations are suggested in an N = 83 isotone for Z (64.PACS number(s): 23.20.En, 23.20.Lv, 23.20.Nx, 27.60. +j

“…In the present work, the spin and parity assignments are based on the previous studies of 142 Pr [23][24][25][26], the measured ADO ratios, and the general yrast arguments (levels populated in heavy-ion reactions usually have spins increasing with increasing excitation energy). Besides, the spin and parity are also assigned with the aid of systematic comparison with the neighboring odd-odd N=83 isotones 144 Pm [10] and 146 Eu [12,27], which is shown in figure 3. Although the data do not allow to make unique spin and parity assignments, we consider most The newly observed transitions and levels are marked in red.…”

High-spin states of the N = 83 nucleus 142Pr have been observed for the first time using the 138Ba(7Li, 3n) reaction at a beam energy of 38 MeV. A total of 40 new transitions and 22 new levels have been identified, leading to a considerable extension of the level scheme of 142Pr. The experimental level structures of 142Pr are compared with its neighboring N = 83 isotones 144Pm and 146Eu. Shell model calculations employing the jj56pna interaction reproduce the experimental findings and provide guidance in the interpretation of the observed high-spin level structures.
