Quadrupole and octupole states in ${}^{152}$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…
