Configuration mixing in the neutron-deficient Pb isotopes
V. Hellemans, S. De Baerdemacker, K. Heyde
In this article we report the results of detailed interacting boson model calculations with configuration mixing for the neutron-deficient Pb isotopes. Calculated energy levels and…
The quadrupole collective model from a Cartan-Weyl perspective
Stijn De Baerdemacker, Kris Heyde, Veerle Hellemans
The matrix elements of the quadrupole variables and canonic conjugate momenta, emerging from collective nuclear models are calculated within a basis. Using a h…
Criticality in the configuration-mixed interacting boson model : (1) mixing
V. Hellemans, P. Van Isacker, S. De Baerdemacker +1
The case of U(5)-- mixing in the configuration-mixed Interacting Boson Model is studied in its mean-field approximation. Phase diagrams with analytical a…
Quadrupole collective variables in the natural Cartan-Weyl basis
S. De Baerdemacker, K. Heyde, V. Hellemans
The matrix elements of the quadrupole collective variables, emerging from collective nuclear models, are calculated in the natural Cartan-Weyl basis of O(5) which is a subgroup of…
