Manifestation of the Berry phase in the atomic nucleus Pb
J. J. Valiente-Dobón, A. Gottardo, G. Benzoni +57
The neutron-rich Pb isotope was produced in the fragmentation of a primary 1 GeV U beam, separated in FRS in mass and atomic number, and then implanted for isom…
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…
A solvable model for octupole phonons
P. Van Isacker
A solvable model is proposed for the description of octupole phonons in closed-shell nuclei, formulated in terms of shell-model par\-ticle--hole excitations. With some simple assum…
