0+ states in the large boson number limit of the Interacting Boson Approximation model (2008)
Bonatsos, Dennis, McCutchan, E. A., Casten, R. F.
Studies of the Interacting Boson Approximation (IBA) model for large boson numbers have been triggered by the discovery of shape/phase transitions between different limiting symmetries of the model....
Simple, empirical order parameter for a first order quantum phase transition in atomic nuclei (2008)
Bonatsos, Dennis, McCutchan, E. A., Casten, R. F., Casperson, R. J.
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 first excited 0+...
Unified description of 0+ states in a large class of nuclear collective models (2008)
Bonatsos, Dennis, McCutchan, E. A., Casten, R. F.
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 potentials that depends...
