Bohr Hamiltonian with Davidson potential for triaxial nuclei
I. Yigitoglu, Dennis Bonatsos
A solution of the Bohr Hamiltonian appropriate for triaxial shapes, involving a Davidson potential in beta and a steep harmonic oscillator in gamma, centered around gamma=30 degree…
Exactly separable version of the Bohr Hamiltonian with the Davidson potential
Dennis Bonatsos, E. A. McCutchan, N. Minkov +5
An exactly separable version of the Bohr Hamiltonian is developed using a potential of the form u(beta)+u(gamma)/beta^2, with the Davidson potential u(beta)= beta^2 + beta_0^4/beta…
Exactly separable version of X(5) and related models
D. Bonatsos, D. Lenis, E. A. McCutchan +2
One-parameter exactly separable versions of the X(5) and X(5)-beta^2 models, labelled as ES-X(5) and ES-X(5)-beta^2 respectively, are derived by using in the Bohr Hamiltonian poten…
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…
