Gamma-soft Analog of the Confined Beta-soft Rotor Model

D. Bonatsos, D. Lenis, N. Pietralla +1

A gamma-soft analog of the confined beta-soft (CBS) rotor model is developed, by using a gamma-independent displaced infinite well beta-potential in the Bohr Hamiltonian, for which…

Analytical Special Solutions of the Bohr Hamiltonian

D. Bonatsos, D. Lenis, D. Petrellis +2

The following special solutions of the Bohr Hamiltonian are briefly described: 1) Z(5) (approximately separable solution in five dimensions with gamma close to 30 degrees), 2) Z(4)…

X(3): An Exactly Separable Gamma-Rigid Version of the X(5) Critical Point Symmetry

Dennis Bonatsos, D. Lenis, D. Petrellis +2

A gamma-rigid version (with gamma=0) of the X(5) critical point symmetry is constructed. The model, to be called X(3) since it is proved to contain three degrees of freedom, utiliz…

Gamma-rigid solution of the Bohr Hamiltonian for gamma = 30 degrees compared to the E(5) critical point symmetry

Dennis Bonatsos, D. Lenis, D. Petrellis +2

A gamma-rigid solution of the Bohr Hamiltonian for gamma = 30 degrees is derived, its ground state band being related to the second order Casimir operator of the Euclidean algebra…

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…

E(5) and X(5) critical point symmetries obtained from Davidson potentials through a variational procedure

Dennis Bonatsos, D. Lenis, N. Minkov +3

Davidson potentials of the form , when used in the E(5) framework, bridge the U(5) and O(6) symmetries, while they bridge the U(5) and SU(3) symmetries when used in…
