Application of a semimicroscopic core-particle coupling method to the backbending in odd deformed nuclei.
In two previous papers, the Kerman-Klein-Dönau-Frauendorf (KKDF) model was used to study rotational bands of odd deformed nuclei. Here we describe backbending for odd nuclei using the same model. The backbending in the neighboring even nuclei is described by a phenomenological two band model, and this core is then coupled to a large single-particle space, as in our previous work. The results ob...
متن کاملDescription of even-even triaxial nuclei within the Coherent State and the Triaxial Rotation Vibration Models
The coherent state model (CSM) and the triaxial rotation-vibration model (TRVM) are alternatively used to describe the ground, γ and β bands of 228Th. CSM is also applied to the nuclei 126Xe and 130Ba, which were recently considered in TRVM. The two models are compared with respect to both their underlying assumptions and to their predicted results for energy levels and E2 branching ratios. Bot...
متن کاملPossible Nuclear Structure Effects in Even-Even Osmium Nuclei
A compilation of the multipole mixing of 2 ' H — v 2 f transitions in 1 8 60s, 1 8 80s, 190Os and 1 9 20s is given. In view of recent results obtained at our laboratory, indicating large anomalies in the conversion process of inhibited M l transitions, the study has been extended for even-even Osmium nuclei. A series of experiments has been performed in which the conversion coefficients and tra...
متن کاملSHELL MODEL STUDY OF EVEN-EVEN Te NEUTRON-RICH NUCLEI
Large-scale shell model calculations were performed for neutron-rich even-even Te using a realistic effective interaction derived from CDBonn nucleon-nucleon potential for the positive and negative parity states. The calculated results are compared with the recently available experimental data. The transition rates B(E2; 0 →2) are also calculated by taking into consideration core polarization e...
متن کاملFermion dynamical symmetry model for the even-even and even-odd nuclei in the Xe-Ba region.
The even–even and even–odd nuclei Xe-Xe and Ba-Ba are shown to have a wellrealized SO8 ⊃ SO6 ⊃ SO3 fermion dynamical symmetry. Their low-lying energy levels can be described by a unified analytical expression with two (three) adjustable parameters for even–odd (even–even) nuclei that is derived from the fermion dynamical symmetry model. Analytical expressions are given for wavefunctions and for...
