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 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 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 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 ...
