Special Solutions of the Bohr Hamiltonian Related to Shape Phase Transitions in Nuclei
Dennis Bonatsos, D. Lenis, D. Petrellis
Nuclei exhibit quantum phase transitions (earlier called ground state phase transitions) between different shapes as the number of nucleons is modified, resulting in changes in the…

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…

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…
