Coherent quadrupole-octupole states from a SUSY-QM Hamiltonian hierarchy and shape invariance
N. Minkov, S. Drenska, P. Yotov
We show that the potential in the radial equation in the model of coherent quadrupole-octupole motion (CQOM) in nuclei generates a sequence of superpotentials and subsequent series…
Non-yrast spectra of odd-A nuclei in a model of coherent quadrupole-octupole motion
N. Minkov, S. Drenska, K. Drumev +3
The model of coherent quadrupole and octupole motion (CQOM) is applied to describe non-yrast split parity-doublet spectra in odd-mass nuclei. The yrast levels are described as low-…
Non-yrast nuclear spectra in a model of coherent quadrupole-octupole motion
N. Minkov, S. Drenska, M. Strecker +2
A model assuming coherent quadrupole-octupole vibrations and rotations is applied to describe non-yrast energy sequences with alternating parity in several even-even nuclei from di…
Nuclear collective motion with a coherent coupling interaction between quadrupole and octupole modes
N. Minkov, P. Yotov, S. Drenska +4
A collective Hamiltonian for the rotation-vibration motion of nuclei is considered, in which the axial quadrupole and octupole degrees of freedom are coupled through the centrifuga…
Parity shift and beat staggering structure of octupole bands in a collective model for quadrupole-octupole deformed nuclei
N. Minkov, P. Yotov, S. Drenska +1
We propose a collective model formalism which describes the strong parity shift observed in low-lying spectra of nuclei with octupole deformations together with the fine rotational…
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…
