Staggering behavior of the low lying excited states of even-even nuclei in a Sp(4,R) classification scheme
We implement a high order discrete derivative analysis of the low lying collective energies of even-even nuclei with respect to the total number of valence nucleon pairs N in the framework of F spin multiplets appearing in a symplectic sp(4, R) classification scheme. We find that for the nuclei of any given F multiplet the respective experimental energies exhibit a ∆N = 2 staggering behavior an...
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...
متن کاملTwo quasi-particle excitations with particle-hole core polarization in even-even single closed shell nuclei
2014 The energies and transition properties of the even-even N = 28, 50 isotones and Z = 28, 50, 82 isotopes are calculated in the framework of the Tamm-Dancoff and Random Phase Approximation, with an effective central interaction in an extended space consisting of two quasiparticle configurations for the open shell and particle-hole configurations for the closed core. Using the results of the ...
