A theoretical description of energy spectra and two-neutron separation energies for neutron-rich zirconium isotopes
J. E. Garcia-Ramos, K. Heyde, R. Fossion +2
Very recently the atomic masses of neutron-rich Zr isotopes, from Zr to Zr, have been measured with high precision. Using a schematic Interacting Boson Model (IBM) H…
New parameterization of Skyrme's interaction for regularized multi-reference energy density functional calculations
K. Washiyama, K. Bennaceur, B. Avez +3
[Background] Symmetry restoration and configuration mixing in the spirit of the generator coordinate method based on energy density functionals have become widely used techniques i…
Configuration mixing in Pb : band structure and electromagnetic properties
V. Hellemans, R. Fossion, S. De Baerdemacker +1
In the present paper, we carry out a detailed analysis of the presence and mixing of various families of collective bands in Pb. Making use of the interacting boson model,…
Spurious finite-size instabilities in nuclear energy density functionals
V. Hellemans, A. Pastore, T. Duguet +5
It is known that some well-established parametrizations of the EDF do not always provide converged results for nuclei and a qualitative link between this finding and the appearance…
Spectral properties of a tractable collective Hamiltonian
S. De Baerdemacker, K. Heyde, V. Hellemans
The spectral properties of a tractable collective model Hamiltonian are studied. The potential energy is truncated up to quartic terms in the quadrupole deformation variables, inco…
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…
