“…The ground-state band GSB with I π =0+, 2+, 4+, ..., and the negative parity band NPB with I π =1 − , 3 − , 5 − .... in even-even nuclei are interwoven, forming a single octupole band with levels characterized by I π =0+, 1−, 2+, 3−, 4+, .... [12][13][14][15][16][17]. This is an example of odd-even staggering or I=1 staggering; the latter term being due to the fact that each energy level with angular momentum I is displaced relatively to its neighbors with angular momenta I= 1 [15].…”

Abstract.The first measured excited states 1 2 E and the ratio of the second to the first measured excited states, the back-bending, the E-GOS and the ratio among the energies of the (I+2) and (I) states as a function of the spin (I) have been drawn to determine the properties of the ground-states band. The odd-even staggering has been drawn to determine the difference between the energies of ground states band (GSB) and negative parity band (NPB). Bohr-Mottelson Model ( BM ), Interacting Boson Model ( IBM-1 ), Interacting Vector Boson Model ( IVBM ) and Doma-El-Gendy (D-G) relation have been used to calculate the energy levels of (GSB), IBM-1 has been used to calculate the energy of the gamma band (GB), while IVBM and BM have been used to calculate the energy levels of (NPB). The calculated energy levels in comparison with the measured data indicated the quality of the fitness presented in this work.

Reduced transition probabilities between the low-lying states of 132 Ba were measured using the Coulomb excitation technique. The experiment was performed at Inter University Accelerator Center (IUAC), New Delhi using a 58 Ni beam of 175 MeV energy to Coulomb excite the 132 Ba nuclei. In addition to the 2 + 1 state, other states in 132 Ba, such as 2 + 2 and 4 + 1 , were populated, the latter for the first time using Coulomb excitation. A set of matrix elements was extracted for the transitions between these levels. These values were determined relative to 134 Ba excitations to minimize the systematic errors. A B(E2; 0 + gs → 2 + 1 ) value of 1.088(85) e 2 b 2 was determined, corresponding to ∼ 54.5 single-particle units.

“…In recent years many works have been done on the structure of Xenon isotopes; Kusakari and M. Sugawara (Kusakari & Sugawara, 1984) calculated the energy levels, the back-bending in the yrast bands , reduced transition probabilities for the positive-parity states of [122][123][124][125][126][127][128][129][130] Xe within the framework of the interacting boson model. Xing-Wang Pan et al (Pan et al, 1996) and Al-Jubbori (Al-Jubbori et al, 2016) described the low-lying energy levels for even-even and even-odd nuclei [126][127][128][129][130][131][132] Ba by a unified analytical expression with two (three) adjustable parameters of the fermion model. Wang Bao-lin (Bao-lin, 1997) calculated the triaxial deformation parameters β and γ in the O(6)-like nuclei by comparing quadrupole moments between the interacting boson model IBM and the collective model studied.…”

In this work, the energy levels electromagnetic transition B(E2) and B(M1), branching ratios, mixing ratios and electric quadrupole moment of even-even [120][121][122][123][124][125][126] Xe isotopes have been investigated using Interacting Boson Model (IBM-1). The results were compared with some previous experimental and theoretical values, it was seen that the obtained theoretical results are in agreement with the experimental data.
