“…The low-lying states showing a rich collective structure in this region were investigated extensively in terms of the pair-truncated shell model (PTSM) [5] and the relativistic Hartree-Fock Model (RHFM) [6]. The Xe [7][8][9][10][11][12][13][14][15][16], Ba [3,[16][17][18] and Te [19][20][21][22][23] region with the mass number A ~ 120-130 has recently been studied experimentally and interpreted by several models [24][25][26][27][28][29][30].

In this work, the ground state, quasi beta and quasi gamma band energies of 114,116,118,120 Xe isotopes have been investigated by using the both (IBM-1 and IBM-2) versions of interacting boson model (IBM). In calculations, the theoretical energy levels have been obtained by using PHINT and NP-BOS program codes. The presented results are compared with the experimental data in respective tables and figures. At the end, it was seen that the obtained theoretical results are in good agreement with the experimental data.

The low spin states of 138 Nd have been reinvestigated via the 124 Te( 19 F,4n1p) reaction at a beam energy of 103 MeV. The quasi-one-phonon γ -vibrational band based on the 1013.7 keV level has been expanded and the quasi-two-phonon γ -vibrational band built on the 1842.7 keV level has been proposed. A systematic comparison supports our assignments for multiphonon γ -vibrational bands in 138 Nd. The characteristics of γ softness in 138 Nd have been discussed. Triaxial projected shell model calculations can well describe the rotational feature of the bands, but they fail to reproduce simultaneously the bandhead energies of the two γ -vibrational bands if a fixed triaxial deformation is assumed.

“…Recently, the Ba and Xe region with mass numbers A≈120 to 130 has been studied experimentally [6,[9][10][11][12][13][14][15] and interpreted by several models: They compare different approaches of the Interacting Boson Approximation (IBA) in the U (5) and the O( 6) limits (with different E2 operators) [7] and the axial Rotation Vibration Model (RVM) and the Asymmetric Rotor Model (ARM) [8]. They exclude the ARM [9,11] because it cannot describe a K=0 band built on γ vibrations [11] and because of the wrong staggering of the 2 + , 3 + , 4 + , 5 + , .…”

Collective quadrupole degrees of freedom give rise to vibrations and rotations in nuclei. The axial Rotation Vibration Model (RVM) is here extended to describe also triaxial equilibrium shapes with β and γ vibrations allowing for the interaction between vibrations and rotations. This Triaxial Rotation Vibration Model (TRVM) is applied to Ba and Xe isotopes with A≈120 to 130. This area has recently been pointed out to be a region for the O(6) limit of the Interacting Boson Approximation (IBA). The present work shows that the TRVM can equally well describe these nuclei concerning their excitation energies and E2 branching ratios.
