Higher-rank discrete symmetries in the IBM. III Tetrahedral shapes
Piet Van Isacker, Abdelhamid Bouldjedri, Salima Zerguine
In the context of the sf-IBM, the interacting boson model with s and f bosons, the conditions are derived for a rotationally invariant and parity-conserving Hamiltonian with up to…
Higher-rank discrete symmetries in the IBM. II Octahedral shapes: Dynamical symmetries
A. Bouldjedri, S. Zerguine, P. Van Isacker
The symmetries of the sdg-IBM, the interacting boson model with s, d and g bosons, are studied as regards the occurrence of shapes with octahedral symmetry. It is shown that no sdg…
Properties of isocalar-pair condensates
P. Van Isacker, A. O. Macchiavelli, P. Fallon +1
It is pointed out that the ground state of n neutrons and n protons in a single-j shell, interacting through an isoscalar (T=0) pairing force, is not paired, J=0, but rather spin-a…
Higher-rank discrete symmetries in the IBM. I Octahedral shapes: general Hamiltonian
P. Van Isacker, A. Bouldjedri, S. Zerguine
In the context of the interacting boson model with , and bosons, the conditions for obtaining an intrinsic shape with octahedral symmetry are derived for a general Hamil…
Consistent description of nuclear charge radii and electric monopole transitions
S. Zerguine, P. Van Isacker, A. Bouldjedri
A systematic study of energy spectra throughout the rare-earth region (even-even nuclei from Ce to W) is carried out in the framework of the interacting boson model (…
Spin-aligned neutron-proton pairs in nuclei
S. Zerguine, P. Van Isacker
A study is carried out of the role of the aligned neutron-proton pair with angular momentum J=9 and isospin T=0 in the low-energy spectroscopy of the nuclei Cd, $^{94}…
