Quadrupole-octupole coupling and the onset of octupole collectivity [PDF]
EPJ Web of ConferencesOctupole deformation and collective excitations are studied within the interacting boson model. By using the results of the self-consistent mean-field calculations with a universal energy density functional, the Hamiltonian of the interacting s, d, and f

Journal of High Energy Physics, 2023 In this paper, we re-investigate the static, soliton-like solutions in the model of the Einstein gravity coupled to a free and complex scalar field, which have been known as mini-boson stars. With the numerical methods, we have discovered a new family of

Spectral fluctuations in the interacting boson model*
Chinese Physics C, 2022 Abstract The energy dependence of the spectral fluctuations in the interacting boson model (IBM) and its connections to the mean-field structures are analyzed by adopting two statistical measures: the nearest neighbor level spacing distribution measuring the chaoticity ...

Negative Doublet Bands with Different Shape in the 107Ag Nucleus [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2022 The existence of chirality in the negative high spin states in the 107Ag nucleus has been confirmed by the Interacting Boson-Fermion Model (IBFM). IBFM excited states and electromagnetic properties are in good agreement with the available experimental ...

Comparative study between IVBM and IBM-2 models to calculate the energy levels for 162-16870Yb isotopes [PDF]
Ядерна фізика та енергетикаThis study uses the interaction vector boson model (IVBM) to identify negative parity band (NPB) energy levels in the 162-16870Yb isotopes series. Simultaneously, the interacting boson model-2 (IBM-2) and the IVBM model were used to determine the ground ...

Collective states of even Xe isotopes in IBM+MQRPA
EPJ Web of Conferences, 2016 A modification of the Quasiparticle Random Phase Approximation (QRPA) with small ground state correlations is suggested. The lowest energy phonon is used as the image of d-boson of the Interacting Boson Model 1 (IBM1) and applied to microscopical ...

Centrifugal stretching of 170Hf in the interacting boson model
EPJ Web of Conferences, 2014 We present the results of a recent experiment to deduce lifetimes of members of the ground state rotational band of 170Hf, which show the effect of centrifugal stretching in this deformed isotope.
