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…

Further explorations of Skyrme-Hartree-Fock-Bogoliubov mass formulas. II: Role of the effective mass

S. Goriely, M. Samyn, M. Bender +1

We have constructed four new complete mass tables, referred to as HFB-4 to HFB-7, each one including all the 9200 nuclei lying between the two drip lines over the range of Z and N>…

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…

Microscopic HFB+QRPA predictions of dipole strength for astrophysics applications

S. Goriely, E. Khan, M. Samyn

Large-scale QRPA calculations of the E1 strength are performed on top of HFB calculations in order to derive the radiative neutron capture cross sections for the whole nuclear char…

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…

Time-Reversal Violating Schiff Moment of 225Ra

J. Engel, M. Bender, J. Dobaczewski +2

We use the Skyrme-Hartree-Fock method, allowing all symmetries to be broken, to calculate the time-reversal-violating nuclear Schiff moment (which induces atomic electric dipole mo…

Self-consistent approach to deformation of intruder states in neutron-deficient Pb and Po

N. A. Smirnova, P. -H. Heenen, G. Neyens

We present systematic calculations of the properties of 11- isomers in neutron-deficient 184-198Pb and 188-200Po. These states are based on the proton (h9/2 i13/2)_{K = 11-} config…

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…

Systematics of Fission Barriers in Superheavy Elements

T. Buervenich, M. Bender, J. A. Maruhn +1

We investigate the systematics of fission barriers in superheavy elements in the range Z = 108-120 and N = 166-182. Results from two self-consistent models for nuclear structure, t…
