Phase Diagram of the Proton-Neutron Interacting Boson Model
arXiv:nucl-th/0410047 · doi:10.1103/PhysRevLett.93.212501
Abstract
We study the phase diagram of the proton--neutron interacting boson model (IBM--2) with special emphasis on the phase transitions leading to triaxial phases. The existence of a new critical point between spherical and triaxial shapes is reported.
