V. G. Gueorguiev, A. I. Georgieva, P. P. Raychev +1
A natural embedding for the corresponding quantum algebras is constructed through the appropriate comultiplication on the generators of each…
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…
"Beat" patterns for the odd-even staggering in octupole bands from a quadrupole-octupole Hamiltonian
N. Minkov, S. B. Drenska, P. P. Raychev +2
We propose a collective Hamiltonian which incorporates the standard quadrupole terms, octupole terms classified according to the irreducible representations of the octahedron group…
Delta I = 2 staggering in rotational bands of diatomic molecules as a manifestation of interband interactions
D. Bonatsos, C. Daskaloyannis, S. B. Drenska +5
It is shown that the recently observed Delta I = 2 staggering seen in superdeformed nuclear bands is also occurring in certain electronically excited rotational bands of diatomic m…
Rotations of nuclei with reflection asymmetry correlations
N. Minkov, S. B. Drenska, P. P. Raychev +2
We propose a collective Hamiltonian which incorporates interactions capable to generate rotations in nuclei with simultaneous presence of octupole and quadrupole deformations. It i…
Delta I = 1 staggering in octupole bands of light actinides: "Beat" patterns
D. Bonatsos, C. Daskaloyannis, S. B. Drenska +4
The Delta I = 1 staggering (odd--even staggering) in octupole bands of light actinides is found to exhibit a ``beat'' behaviour as a function of the angular momentum I, forcing us…
