Consistent description of nuclear charge radii and electric monopole transitions
TL;DR: In this article, a systematic study of energy spectra throughout the rare earth region was carried out in the framework of the interacting boson model (IBM), leading to an accurate description of the spherical-to-deformed shape transition in the different isotopic chains.

Phase transitions in the sdg interacting boson model
TL;DR: In this article, a phase-transitional structure is established for a schematic sdg hamiltonian which is intermediate between four dynamical symmetries of U(15), namely the spherical U(5) ⊗ U(9), the (prolate and oblate) deformed SU±(3) and the 2-soft SO(15) limits.

Spin-aligned neutron-proton pairs in N = Z nuclei
S. Zerguine,P. Van Isacker +1 more
TL;DR: In this article, the role of the aligned neutron-proton pair with angular momentum $J=9$ and isospin $T=0$ in the low-energy spectroscopy of the $N=Z$ nuclei was investigated.

Higher-rank discrete symmetries in the IBM. I Octahedral shapes: general Hamiltonian
TL;DR: In this paper, the conditions for obtaining an intrinsic shape with octahedral symmetry for a general Hamiltonian with up to two-body interactions were derived for the interacting boson model with $s$, $d$ and $g$ bosons.

Higher-rank discrete symmetries in the IBM. II Octahedral shapes: Dynamical symmetries
TL;DR: In this article, it was shown that no sdg-IBM Hamiltonian with dynamical symmetry displays in its classical limit an isolated minimum with octahedral shape, either an octahedron or a cube, may arise through a modification of two-body interactions between the g bosons.
