Probing Quadruple Deformation in Transitional Nuclei via Angular Momentum Projection
Xian-Zhi Zhao, Sheng-Nan Wang, Yu Zhang
Within the interacting boson model (IBM), a geometric analysis of transitional nuclei is carried out through angular momentum projection of the intrinsic coherent state. The result…
Anomalous collective modes in atomic nuclei within the proton-neutron interacting boson model
Wei Teng, Yu Zhang, Sheng-Nan Wang +3
Novel collective modes characterized by a ratio () less than 1.0 that were observed recently have been i…
Understanding Xe isotopes near through the prolate-oblate shape phase transition
Wei Teng, Sheng-Nan Wang, Yu Zhang
A simple algebraic scheme incorporating the prolate-oblate shape phase transition (SPT) is proposed within the framework of the interacting boson model to describe the quadrupole d…
Triaxial rotor modes in finite-N boson systems
Yu Zhang, ShengNan Wang, Feng Pan +2
We propose an algebraic approach to elucidate the dynamic characteristics of triaxial rotor modes in nuclei by mapping a triaxial rotor Hamiltonian to the interacting boson model (…
The IBM Description of the B(E2) Anomaly: Dynamical Triaxiality and Configuration Mixing
Wei Teng, Sheng Nan Wang, Xian Zhi Zhao +1
A theoretical investigation has been carried out to examine the effects of dynamical triaxility and configuration mixing on the anomaly, characterized by $B_{4/2}=B(E2;4_1^…
Quadrupole and octupole states in Sm using the proton-neutron interacting boson model
Bao-Yue Hu, Yu Zhang, Gui-Xiu Na +2
A scheme of solving the proton-neutron interacting boson model (IBM-2) in terms of the SU(3) basis is introduced, by which the IBM-2 coupled with an octupole boson is applied to de…
