W(5): Wobbling Mode in the Framework of the X(5) Model
Dennis Bonatsos, D. Lenis, D. Petrellis +1
Using in the Bohr Hamiltonian the approximations leading to the Bohr and Mottelson description of wobbling motion in even nuclei, a W(5) model for wobbling bands, coexisting with a…
Molecular Spectra from Rotationally Invariant Hamiltonians Based on the Quantum Algebra SUq(2) and Irreducible Tensor Operators under SUq(2)
Dennis Bonatsos, B. A. Kotsos, P. P. Raychev +1
The rotational invariance under the usual physical angular momentum of the SUq(2) Hamiltonian for the description of rotational molecular spectra is explicitly proved and a connect…
Staggering effects in nuclear and molecular spectra
D. Bonatsos, N. Karoussos, C. Daskaloyannis +5
It is shown that the recently observed Delta J = 2 staggering effect (i.e. the relative displacement of the levels with angular momenta J, J+4, J+8, ..., relatively to the levels w…
Quantum Algebraic Symmetries in Nuclei, Molecules and Atomic Clusters
Dennis Bonatsos, C. Daskaloyannis
Various applications of quantum algebraic techniques in nuclear structure physics and in molecular physics are briefly reviewed and a recent application of these techniques to the…
Parafermionic and Generalized Parafermionic Algebras
Dennis Bonatsos, C. Daskaloyannis, K. Kanakoglou
The general properties of the ordinary and generalized parafermionic algebras are discussed. The generalized parafermionic algebras are proved to be polynomial algebras. The ordina…
Symmetries in nuclei and molecules
Dennis Bonatsos, P. Kolokotronis, D. Lenis +6
Recent progress in two different fronts is reported. First, the concept of bisection of a harmonic oscillator (HO) or hydrogen atom (HA), used in the past in establishing the conne…
