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…

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…

Nonlinear extension of the u(2) algebra as the symmetry algebra of the planar anisotropic quantum harmonic oscillator with rational ratio of frequencies and ``pancake'' nuclei
Dennis Bonatsos, C. Daskaloyannis, P. Kolokotronis +1
The symmetry algebra of the two-dimensional anisotropic quantum harmonic oscillator with rational ratio of frequencies, which is characterizing ``pancake'' nuclei, is identified as…
