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 کاملExtending the two to one Relationship Between the Spectra of Even-Even and Neighbouring Even-Odd Nuclei
In the single j shell there is a two to one relationship between the spectra of certain even-even and neighbouring even-odd (or odd-even) nuclei e.g. the calculated energy levels of J=0+ states in 44Ti are at twice the energies of corresponding levels in 43Ti(43Sc) with J=j=7/2. Here an approximate extension of the relationship is made by making a truncation in seniority e.g. for 46Ti and 45Sc ...
