“…Neutron excitations across the N=82 closure was proposed to be involved in the N=83 isotones, 134 Sb, 135 [15,16], and 149 Dy [17]. In addition, high-spin isomers were also found systematically [9][10][11][12][13][14][15][16][17] in the N=83 isotones. Their excitation energies and half-lives were found to be almost the same as 8.5 MeV and 1 μs, respectively.…”

“…High-spin states of the N=83 isotones with proton number greater than 59 have been investigated in detail experimentally [9][10][11][12][13][14][15][16][17]. The neutron core excitations and high-spin isomers have also been systematically reported in the N=83 isotones [9][10][11][12][13][14][15][16][17][18][19]. In contrast to the detailed high-spin studies in the heavier isotones, high-spin states of 142 Pr (Z=59) were practically unknown before the present work.…”

“…The level structures of these isotones should be reasonably described by the shell model. High-spin states of the N=83 isotones with proton number greater than 59 have been investigated in detail experimentally [9][10][11][12][13][14][15][16][17].

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.

High-spin isomer and level structure of 145Sm

et al. 1997

View full text Add to dashboard Cite

A high-spin isomer in 145 Sm was discovered by using Inverse kinematic reactions, 20 Ne e Xe,a7n) 145 Sm and 16 0 e 36 Xe,7n) 145 Sm. The half life was determined to be 0.96 J.LSec. Sixty-five 1-rays were identified by the /')'-coincidence measurements to belong to the isomer decay. The low-lying level scheme of 145 Sm was established in detail by the in-beam 1-ray measurements using the 139 La e 0 B,4n) 145 Sm reaction. A complex decay scheme of this isomer was constructed by using the data obtained from the 136 Xe induced reactions, combining the informations of low-lying states mentioned above. The excitation energy of this isomer was determined to be 8.8 MeV. The /')'-coincidence measurement using the 138 Ba (13 C,6n) 145 Sm reaction was also performed. Based on this information, the level scheme above the high-spin isomer was extended up to the state at 14.6 MeV. A 1-ray angular distribution measurement using the same reaction with pulsed beam was carried out and was used to assign a spin value of each level. Low-lying states in 145 Sm were interpreted to originate from a single neutron coupled to the 144 Sm core excitation. Experimental yrast states were compared with a calculation of a deformed independent particle model (DIPM). A configuration of the high-spin isomer was deduced by the DIPM calculation to be { 7r h ll /2 2 v (f 7 /2 h 9/2 i 13/2) } 49/2+ .
