Test of the proton-neutron interacting boson-fermion model in the region around A=190
(American Physical Society, 1986)
We present systematic calculations on nuclei in the region around A=190 within the framework of the proton-neutron interacting boson-fermion model. Energy levels and electromagnetic properties of both positive and negative ...

Hartree-Bose mean-field approximation for the interacting boson model (IBM-3)
(American Physical Society, 1998-02-01)
A Hartree-Bose mean-field approximation for the IBM-3 is presented. A Hartree-Bose transformation from spherical to deformed bosons with charge-dependent parameters is proposed which allows bosonic pair correlations and ...

Phase diagram of the proton-neutron interacting boson model
(American Physical Society, 2004-11-19)
We study the phase diagram of the proton-neutron interacting boson model with special emphasis on the phase transitions leading to triaxial phases. The existence of a new critical point between spherical and triaxial shapes ...
