Global study of quadrupole correlation effects
M. Bender, G. F. Bertsch, P. -H. Heenen
We discuss the systematics of ground-state quadrupole correlations of binding energies and mean-square charge radii for all even-even nuclei, from O16 up to the superheavies, for w…
Systematics of quadrupolar correlation energies
M. Bender, G. F. Bertsch, P. -H. Heenen
We calculate correlation energies associated with the quadrupolar shape degrees of freedom with a view to improving the self-consistent mean-field theory of nuclear binding energie…
Configuration mixing of angular momentum projected self-consistent mean-field states for neutron-deficient Pb isotopes
M. Bender, P. Bonche, T. Duguet +1
We study the low-lying collective excitation spectra of the neutron-deficient lead isotopes Pb182-Pb194 by performing a configuration mixing of angular-momentum and particle-number…
Correlation energies by the generator coordinate method: computational aspects for quadrupolar deformations
M. Bender, G. Bertsch, P. -H. Heenen
We investigate truncation schemes to reduce the computational cost of calculating correlations by the generator coordinate method based on mean-field wave functions. As our test nu…
Beyond-mean-field-model analysis of low-spin normal-deformed and superdeformed collective states of S32, Ar36, Ar38 and Ca40
M. Bender, H. Flocard, P. -H. Heenen
We investigate the coexistence of spherical, deformed and superdeformed states at low spin in S32, Ar36, Ar38 and Ca40. The microscopic states are constructed by configuration mixi…
Skyrme mean-field study of rotational bands in transfermium isotopes
M. Bender, P. Bonche, T. Duguet +1
Self-consistent mean field calculations with the SLy4 interaction and a density-dependent pairing force are presented for nuclei in the Nobelium mass region. Predicted quasi-partic…
