Physical Review C. Vol. 73, n. 5 (2006). ISSN 0556-28130556-2813http://hdl.handle.net/10272/5459We introduce a simple two-level boson model with the same energy surface as the Q-consistent Interacting Boson Model Hamiltonian. The model can be diagonalized for large number of bosons and the results used to check analytical finite-size corrections to the energy gap and the order parameter in the critical region.spaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/BosonesBoson modeljournal articleopen access
