Axially symmetric quadrupole-octupole incorporating sextic potential

We present an extended application of the analytic quadrupole octupole axially symmetric model, originally employed to study the octupole deformation and vibrations in light actinides using an infinite well potential (IW). In this work, we extend the model's applicability to a broader range of nuclei exhibiting octupole deformation by incorporating a sextic potential instead of the Davidson potential. Similarly to conventional models, such as AQOA-IW (for infinite square potential) and AQOA-D (for the Davidson potential), our proposed model is referred to as AQOA-S. By employing the sextic potential, phenomenologically represented as v (β˜)= a 1 β˜ 2+ a 2 β˜ 4+ a 3 β˜ 6, we can derive analytical expressions for the energy spectra and transition rates (B (E1), B (E2), B (E3)). The energy spectra of the model are essentially governed by two critical parameters: ϕ 0, indicating the balance between octupole and quadrupole …

Numerical calculations of the isoscalar giant monopole resonance (ISGMR) strength in even-even Zr isotopes are presented using the quasiparticle finite amplitude method based on the deformed relativistic Hartree–Bogoliubov theory, employing the DD-PCX and DD-PC1 effective interactions. A satisfactory agreement with the available experimental ISGMR strength is achieved for Zr. Through constraint calculations in the (,)-plan, we identify local minima corresponding to axial and triaxial shapes in the even-even Zr isotopes. A soft monopole mode observed near 15 MeV in Zr and around 13 MeV in Zr can be explained not only by the deformation-induced coupling between the ISGMR and the isoscalar giant quadrupole resonance (ISGQR) strength, but also by the influence of neutron excess. The ISGMR is best described by the DD-PCX force, having a low value of the incompressibility value of …

The phenomena of shape evolution and shape coexistence within the Molybdenum isotopic chain are investigated using the covariant density functional theory with the parameterizations DD-ME2 and DD-PC1. Furthermore, various ground state properties of this chain are investigated, including binding energy, two-neutron separation energy, charge radii, and two-neutron shell gap. A robust agreement is observed when comparing with the available experimental data. The ground state deformation of Mo isotopes evolves smoothly and correlates with the continuous and gradual changes observed in the physical properties. A noticeable phenomenon of shape coexistence can be observed in certain isotopes, marked by the simultaneous existence of both a triaxial and an oblate axial minimum. A pronounced and well-defined shell closure is prominently evident at the neutron magic number N= 82.

In a recent paper (S. Ait El Korchi et al. (2020) [32]), we explored, inside the context of Critical Point Symmetries (CPSs) X(3) and Z(4), a correlation between two exceedingly known quantum concepts, the Minimal Length (ML) and the Deformation-Dependent Mass (DDM), that are commonly applied in various areas of physics. Such a correlation has been strongly identified in transition nuclei by calculating some physical observables of that quantum system, like as energy spectra, moments of inertia and transition probabilities. In this paper we extend that study to E(5) dynamical symmetry corresponding to the shape phase transition U(5)↔O(6). The experimental realization of the models was found to occur in some nuclei, using the existing phenomenological potentials: Infinite Square Well, Davidson and Kratzer, whose models fits provide the best agreement. Importantly the calculations performed in this work …

An investigation of the Davydov-Chaban Hamiltonian with Kratzer potential for the variable β and γ fixed to π/6, is performed by taking into account a deformation-dependent mass term. The energies and wave functions of the eigenvalue problem are obtained in compact form by using the asymptotic iteration method. The numerical results of the energy spectrum and the electric quadrupole transition ratios are calculated and compared with the experimental data for 128,130,132 Xe and 192,194,196 Pt nuclei as well as other theoretical models. In this way, it is highlighted the importance had by the effect of the shape flatness of the Kratzer potential and the deformation dependent mass term on the numerical predictions in relation to the experimental data.

In this work, the Davydov-Chaban Hamiltonian, describing the collective motion of γ-rigid atomic nuclei, is amended by allowing the mass parameter to depend on the nuclear deformation. Further, Z (4)-DDM (Deformation-Dependent Mass) model is proposed by considering the Kratzer potential for the β variable, and solving the problem by techniques of asymptotic iteration method (AIM). The results of the calculated spectra and B (E2) transition rates for series of 192− 196Pt isotopes are compared with the corresponding experimental data as well as with other theoretical models. Exact analytical expressions are derived for spectra and normalized wave functions of the Kratzer potential. The obtained results show an overall good agreement with the experimental data and an important improvement in respect to other models.

In this paper, we present a new study about decay process in the framework of the quantum concept, namely: the position dependent mass formalism. Such a study allowed us to obtain a new generalized formula for decay half-lives which enables us to rebuild the majority of the formulas existing in the literature. Moreover, from this generalized formula, we derived two new practical ones. We have tested these two latter on 397 nuclei (). By comparing our obtained results with those from the majority of semi-empirical formulas in the literature, it comes out that one of these two new proposed formulas is the most precise one inasmuch as it presents the lowest r.m.s deviation in respect to the experimental data particularly for even–even nuclei. Based on this new formula, we make predictions for some super-heavy nuclei.

In the present paper, we study the collective states of even–even nuclei in γ-rigid mode within the sextic potential and the minimal length (ML) formalism in Bohr–Mottelson model. The eigenvalues problem for the latter is solved by combined means of quasi-exact solvability and a quantum perturbation method. Numerical calculations are performed for 35 nuclei: 98− 108 Ru, 100− 102 Mo, 116− 130 Xe, 180− 196 Pt, 172 Os, 146− 150 Nd, 132− 134 Ce, 154 Gd, 156 Dy and 150− 152 Sm. Through this study, it appears that our elaborated model leads to an improved agreement of the theoretical results with the corresponding experimental data by reducing the rms with a rate going up to 63% for some nuclei. This comes from the fact that we have combined the sextic potential, which is a very useful phenomenological potential, with the formalism of the ML, which is based on the generalized uncertainty principle and …

Correlation between two quantum concepts within shape phase transitions in nuclei

The present work consists in studying a correlation that we have observed, for the first time, between two well-known quantum concepts, namely: the Minimal Length (ML) and the Deformation-Dependent Mass (DDM) which are widely used in different fields of physics. This correlation was revealed in transitional nuclei near the Critical Point Symmetries (CPS) X (3) and Z (4) through calculations of their energy spectra, moments of inertia and transition probabilities. Based on this correlation which could be considered as a new signature for CPS, we have found eventual new candidate nuclei for these critical points.

Nuclear mass is a key property of atomic nuclei. The accurate determination of nuclear masses provides information for the nuclear shell structure and nuclear deformations. The FRS Ion Catcher experimental setup at GSI, Darmstadt was used to perform mass measurements of 252 Cf fragments using a multiple-reflection time-of-flight mass spectrometer. The reported results are compared to previous measurements and their implication in the estimation of two-neutron separation energy is discussed.

In this work, we present a new version of the Bohr collective Hamiltonian for triaxial nuclei within deformation-dependent mass formalism (DDM) using the Hulthén potential. We shall call the developed model Z(5)-HD. Analytical expressions for energy spectra are derived by means of the recent version of the asymptotic iteration method. The calculated numerical results of energies and B(E2) transition rates are compared with the experimental data, and several theoretical results from Z(5) model, the model Z(5)-H using the Hulthén potential without DDM formalism as well as theoretical predictions of Z(5)-DD model with Davidson potential using DDM formalism. The obtained results show an overall agreement with experimental data and an important improvement in respect to the other models.

Some experimental data indicate that the mass tensor of collective Bohr Hamiltonian should be considered as a function of the collective coordinates rather than a constant (Bonatsos et al. in Phys Rev C 83:044321, 2011). In this work, our purpose is to investigate the properties of low-lying collective states of the odd nuclei Yb and Dy by using a new generalized version of the collective quadrupole Bohr Hamiltonian with deformation-dependent mass coefficients. The proposed new version of the Bohr Hamiltonian is solved for Davidson potential in shape variable, while the potential is taken to be equal to the harmonic oscillator. The obtained results of the excitation energies and B(E2) reduced transition probabilities show an overall agreement with the experimental data. Moreover, we investigate the effect of the deformation-dependent mass parameter on energy spectra and transition rates in both cases …
