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 کاملOdd-Even Staggering of Nuclear Masses: Pairing
The odd-even staggering of nuclear masses was recognized in the early days of nuclear physics. Recently, a similar e ect was discovered in other nite fermion systems, such as ultrasmall metallic grains and metal clusters. It is believed that the staggering in nuclei and grains is primarily due to pairing correlations (superconductivity), while in clusters it is caused by the Jahn-Teller e ect. ...
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 کاملRevisiting the Even-odd Staggering in Fission-fragment Yields
The even-odd staggering observed in the experimental fission-fragment nuclear-charge yields is investigated over a wide systematics of fission fragments measured at Lohengrin in direct kinematics and at GSI in inverse kinematics. The general increase of the even-odd staggering in the fission-fragment charge yields towards asymmetric charge splits is explained by the absorption of the unpaired n...
متن کاملQuasi-SU(3) truncation scheme for even-even sd-shell nuclei
Abstract The quasi-SU(3) symmetry was uncovered in full pf and sdg shell-model calculations for both even-even [1] and odd-even nuclei [2]. It manifests itself through a dominance of single-particle and quadrupole-quadrupole terms in a Hamiltonian used to describe welldeformed nuclei. A practical consequence of the quasi-SU(3) symmetry is an efficient basis truncation scheme. In [3] it is shown...
