“…In particular, the 6 + 1 state is dominated by two valence protons and is relatively unaffected by the increase of neutrons, the 6 + 1 states remain at a nearly constant excitation energy for even-even 122−130 Te isotopes [3]. By introducing the dipole interaction term into the Hamiltonian [41][42][43], the structure of the yrast bands including the 6 + 1 level are reproduced by the theoretical predications. Similar to the 6 + 1 state, the observed energy of 4 + 2 level is only changed about 135 keV from 122 Te to 130 Te isotopes.…”

Based on the neutron and proton degrees of freedom, the low-lying energy levels, the E2, M 1 and E0 transition strengths of nucleus 124 Te have been calculated by the neutron-proton interacting boson model. The calculated results are quite consistent with the experimental data. By comparing the key observables of states at the critical point of U πν (5)-O πν (6) transition with experimental data and calculated results, we show that the 124 Te is a possible nucleus at the critical point of the second order phase transition from vibration to unstable rotation and such a critical point contains somewhat triaxial rotation. The 0 + 2 state of 124 Te can be interpreted as the lowest state of the first excited family of intrinsic levels in the critical point symmetry.

“…Only the dipole interaction term Lπ • Lπ is explicitly considered in the Hamiltonian because of only one hole-like neutron boson outside the N = 50 shell in 80 Ge. Lπ • Lπ plays an important role on the description of rotational energy levels [43][44][45]. The parameter ω ππ can be used to tune the order of the 2 + 2 state and 4 + 1 state.…”

The properties of the low-lying states, especially the relevant shape coexistence in 80 Ge close to one of most neutron-rich doubly magic nuclei at N = 50 and Z = 28 have been investigated within the framework of the proton-neutron interacting model (IBM-2). Based on the fact that the relative energy of the d neutron boson is different from proton bosons', the calculated energy levels of low-lying states, E2 transition strengths can reproduce the experimental data very well.Particularly, the first excited state 0 + 2 is reproduced quite nicely, which is intimately related with the shape coexistence phenomenon. And the ρ 2 (E0, 0 + 2 → 0 + 1 ) transition strength has been predicted.The experimental data and theoretical results indicate that both collective spherical and γ-soft vibration structures coexist in 80 Ge.

“…Theoretically, studies of nuclear properties by applying the boson model versions have been extended to all types of nuclei [1][2][3][4][5][6]. The excitations dealt with symmetry in the properties of energy levels [7][8][9]. Experimentally, collective low-lying 1 + states have been observed in several deformed rare-earth nuclei [10][11][12].…”

The characteristics of low-lying mixed-symmetry states in 158-168Hf isotopes have been investigated in the framework of the interacting boson model. The obtained results of the low energy spectra, B(E2) and mixing ratio δ(E2/M1) for all isotopes are compared with empirical values . The effect of the Majrona terms on the energy levels have been investigated. The 2ms+ and 1+ states are the lowest mixed-symmetry for vibrational 158-164Hf nuclei and for rotational 166,168Hf nuclei, respectively.
