Mean-field description of ground-state properties of drip-line nuclei: Pairing and continuum effects

J. Dobaczewski, W. Nazarewicz, T. R. Werner +3

Ground-state properties of exotic even-even nuclei with extreme neutron-to-proton ratios are described in the framework of the self-consistent mean-field theory with pairing formul…

Z=110--111 Elements and the Stability of Heavy and Superheavy Elements

C. L. Wu, M. Guidry, D. H. Feng

The recent discovery of isotopes with Z=110--111 suggests evidence for (1) a monopole--monopole interaction that does not appear explicitly in Nilsson--Strutinsky mass systematics,…

SMMC method for two-neutrino double beta decay

P. B. Radha, D. J. Dean, S. E. Koonin +5

Shell Model Monte Carlo (SMMC) techniques are used to calculate two-neutrino double beta decay matrix elements. We validate the approach against direct diagonalization for C…

The fermion dynamical symmetry model for the even--even and even--odd nuclei in the Xe--Ba region

X. W. Pan, J. L. Ping, D. H. Feng +2

The even--even and even--odd nuclei Xe-Xe and Ba-Ba are shown to have a well-realized fermion dynamical symmetry. T…

Solution of the Nuclear Shell Model by Symmetry-Dictated Truncation

M. W. Guidry, D. H. Feng, X. W. Pan +1

The dynamical symmetries of the Fermion Dynamical Symmetry Model are used as a principle of truncation for the spherical shell model. Utilizing the usual principle of energy-dictat…

Shell Model Monte Carlo Studies of -Soft Nuclei

Y. Alhassid, G. F. Bertsch, D. J. Dean +1

We present Shell Model Monte Carlo calculations for nuclei within the full major shell 50-82 for both protons and neutrons. The interaction is determined solely by self-consistency…

Isospin-mixing corrections for fp-shell Fermi transitions

W. E. Ormand, B. A. Brown

Isospin-mixing corrections for superallowed Fermi transitions in {\it fp}-shell nuclei are computed within the framework of the shell model. The study includes three nuclei that ar…

Consistent Treatment of Propagator Modifications in Elastic Nucleon-Nucleus Scattering within the Spectator Expansion

C. R. Chinn, Ch. Elster, R. M. Thaler +1

The theory of the elastic scattering of a nucleon from a nucleus is presented in the form of a Spectator Expansion of the optical potential. Particular attention is paid to the tre…

GCM study of hexadecapole correlations in superdeformed Hg

P. Magierski, P. -H. Heenen, W. Nazarewicz

The role of hexadecapole correlations in the lowest superdeformed band of Hg is studied by self consistent mean field methods. The generator coordinate method with particle…

Universality of Symmetry and Mixed-symmetry Collective Nuclear States

B. H. Smith, X. P. Pan, D. H. Feng +1

The global correlation in the observed variation with mass number of the and summed transition strengths is examined for rare earth nuclei. It is shown that a theory of c…
