SU(3) quasidynamical symmetry underlying the Alhassid--Whelan arc of regularity
Dennis Bonatsos, E. A. McCutchan, R. F. Casten
The first example of an empirically manifested quasi dynamical symmetry trajectory in the interior of the symmetry triangle of the Interacting Boson Approximation model is identifi…
Complementary descriptions of shape/phase transitions in atomic nuclei
Dennis Bonatsos, E. A. McCutchan, N. V. Zamfir
Shape/phase transitions in atomic nuclei have first been discovered in the framework of the Interacting Boson Approximation (IBA) model. Critical point symmetries appropriate for n…
What can we learn from the Interacting Boson Model in the limit of large boson numbers?
Dennis Bonatsos, E. A. McCutchan, R. F. Casten
Over the years, studies of collective properties of medium and heavy mass nuclei in the framework of the Interacting Boson Approximation (IBA) model have focused on finite boson nu…
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…
Unified description of 0+ states in a large class of nuclear collective models
Dennis Bonatsos, E. A. McCutchan, R. F. Casten
A remarkably simple regularity in the energies of 0+ states in a broad class of collective models is discussed. A single formula for all 0+ states in flat-bottomed infinite potenti…
Simple, empirical order parameter for a first order quantum phase transition in atomic nuclei
Dennis Bonatsos, E. A. McCutchan, R. F. Casten +1
A simple, empirical signature of a first order phase transition in atomic nuclei is presented, the ratio of the energy of the 6+ level of the ground state band to the energy of the…
