Gamow-Teller strength and the spin-isospin coupling constants of the Skyrme energy functional

M. Bender, J. Dobaczewski, J. Engel +1

We investigate the effects of the spin-isospin channel of the Skyrme energy functional on predictions for Gamow-Teller distributions and superdeformed rotational bands. We use the…

Dissociation of Heavy Quarkonia in the Quark-Gluon Plasma

Cheuk-Yin Wong

Using a temperature-dependent potential obtained from lattice gauge calculations, we study the stability of heavy quarkonia in the quark-gluon plasma. We find that only the Upsilon…

Dissociation of a Heavy Quarkonium at T<T_c

Cheuk-Yin Wong, Ted Barnes, Eric S. Swanson +1

We examine three different ways a heavy quarkonium can dissociate at temperatures below the quark-gluon plasma phase transition temperature T_c: spontaneous dissociation, dissociat…

The Z=82 shell closure in neutron-deficient Pb isotopes

M. Bender, T. Cornelius, G. A. Lalazissis +3

Recent mass measurements show a substantial weakening of the binding energy difference delta_{2p} (Z,N) = E(Z-2,N) - 2 E(Z,N) + E(Z+2,N) in the neutron-deficient Pb isotopes. As de…

Dissociation of a Heavy Quarkonium at High Temperatures

Cheuk-Yin Wong

We examine three different ways a heavy quarkonium can dissociate at high temperatures. The heavy quarkonium can dissociate spontaneously when it becomes unbound at a temperature a…

Heavy Quarkonium Dissociation Cross Sections in Relativistic Heavy-Ion Collisions

Cheuk-Yin Wong, E. S. Swanson, T. Barnes

Many of the hadron-hadron cross sections required for the study of the dynamics of matter produced in relativistic heavy-ion collisions can be calculated using the quark-interchang…

Relativistic Generalization of the Post-Prior Equivalence for Reaction of Composite Particles

Cheuk-Yin Wong, Horace W. Crater

In the non-relativistic description of the reaction of composite particles, the reaction matrix is independent of the choice of post or prior forms for the interaction. We generali…

Benchmark Test Calculation of a Four-Nucleon Bound State

H. Kamada, A. Nogga, W. Gloeckle +15

In the past, several efficient methods have been developed to solve the Schroedinger equation for four-nucleon bound states accurately. These are the Faddeev-Yakubovsky, the couple…

Shell stabilization of super- and hyperheavy nuclei without magic gaps

M. Bender, W. Nazarewicz, P. -G. Reinhard

Quantum stabilization of superheavy elements is quantified in terms of the shell-correction energy. We compute the shell correction using self-consistent nuclear models: the non-re…

Pairing Interaction and Self-Consistent Densities in Neutron-Rich Nuclei

J. Dobaczewski, W. Nazarewicz, P. -G. Reinhard

Particle and pairing densities in spherical even-even neutron-rich nuclei are studied within the Skyrme-Hartree-Fock-Bogoliubov approach with the density-dependent pairing interact…

The nuclear quadrupole moment of 57Fe from microscopic nuclear and atomic calculations

Gabriel Martinez-Pinedo, Peter Schwerdtfeger, Etienne Caurier +3

The nuclear quadrupole moment of the I=3/2- excited nuclear state of 57Fe at 14.41 keV, important in Mössbauer spectroscopy, is determined from the large-scale nuclear shell-model…
