Octupole deformation in light actinides within an analytic quadrupole octupole axially symmetric model with Davidson potential
Dennis Bonatsos, Andriana Martinou, N. Minkov +2
The analytic quadrupole octupole axially symmetric model, which had successfully predicted 226Ra and 226Th as lying at the border between the regions of octupole deformation and oc…
Bohr Hamiltonian with deformation-dependent mass term for the Kratzer potential
Dennis Bonatsos, P. E. Georgoudis, N. Minkov +2
The Deformation Dependent Mass (DDM) Kratzer model is constructed by considering the Kratzer potential in a Bohr Hamiltonian, in which the mass is allowed to depend on the nuclear…
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…
Symmetries and staggering effects in nuclear rotational spectra
N. Minkov, S. B. Drenska, P. P. Raychev +2
We study the fine structure of nuclear rotational spectra on the basis of both dynamical and discrete symmetry approaches. In this framework we show that the odd--even (Delta I = 1…
