VAN ISACKER, P; MORALES, I; VARGAS, C.E  e  FRANK, A. The geometry and phase transition behavior of configuration mixing in the interacting boson model. Rev. mex. fis. [online]. 2006, vol.52, suppl.1, pp.5-11. ISSN 0035-001X.

The Interacting Boson Model (IBM) with configuration mixing can be given a geometrical interpretation, when used in conjunction with a (matrix) coherent-state method. This approach can be used to study the geometric aspects of shape coexistence in nuclei, as well as the phase space diagrams associated to this phenomenon.
