Sequence of Potentials Interpolating between the U(5) and E(5) Symmetries
Dennis Bonatsos, D. Lenis, N. Minkov +2
It is proved that the potentials of the form (with being integer) provide a ``bridge'' between the U(5) symmetry of the Bohr Hamiltonian with a harmonic oscillator pot…
Odd-Even Staggering in Octupole Bands of Actinides and Rare Earths: Systematics of "Beat" Patterns
Dennis Bonatsos, C. Daskaloyannis, S. B. Drenska +4
``Beat'' patterns are shown to appear in the octupole bands of several actinides and rare earths, their appearance being independent from the formula used in order to isolate and d…
Simplified boson realization of the subalgebra of and matrix elements of quadrupole operators
P. P. Raychev, R. P. Roussev, P. A. Terziev +2
A simplified boson realization of the subalgebra of is constructed. A simplified form of the corresponding basis states is obtained. The reduced matrix…
and bifurcations in rotational bands of diatomic molecules
Dennis Bonatsos, C. Daskaloyannis, G. A. Lalazissis +4
It is shown that the recently observed bifurcation seen in superdeformed nuclear bands is also occurring in rotational bands of diatomic molecules. In addition, signs of a $…
