Abstract

Proton-neutron correlation energies extracted from double differences in binding energies, obtained from theoretical masses calculated within the Skyrme density functional theory with contact pairing interaction, are compared with experimental values based on the 2003 nuclear mass compilation. It is shown that theory gives a qualitative (and often quantitative) reproduction of experiment. The agreement is particularly good for deformed nuclei. For transitional systems, the comparison suggests that more theoretical work is required to incorporate dynamic correlations that go beyond the mean-field theory.

Charged-particle (pseudo-)rapidity distributions in p+p/p+p and Pb+Pb/Au+Au collisions from UrQMD calculations at energies available at the CERN Super Proton Synchrotron to the Large Hadron Collider

Journal Article Mitrovski, Michael ; Petersen, Hannah ; Institut fuer Theoretische Physik, Goethe-Universitaet, Max-von-Laue-Str. 1, D-60438 Frankfurt am Main ; ... - Physical Review. C, Nuclear Physics

We present results for final state charged-particle (pseudo-)rapidity distributions in p+p/p+p and Pb+Pb/Au+Au at ultra high energies (17.3 GeV{<=}{radical}(s{sub NN}){<=}14 TeV) from the Ultra-relativistic Quantum Molecular Dynamics (UrQMD-v2.3) model. In addition, excitation functions of produced charged-particle multiplicities (N{sub ch}) and pseudorapidity spectra are investigated up to CERN Large Hadron Collider energies. Good agreement is observed between UrQMD and measured pseudorapidity distributions of charged particles up to the highest Tevatron and SppS energies.

QUANTIFYING THE SIGNIFICANCE OF THE MAGNETIC FIELD FROM LARGE-SCALE CLOUD TO COLLAPSING CORE: SELF-SIMILARITY, MASS-TO-FLUX RATIO, AND STAR FORMATION EFFICIENCY

Journal Article Koch, Patrick M. ; Ho, Paul T. P. ; Tang, Ya-Wen, E-mail: pmkoch@asiaa.sinica.edu.tw - Astrophysical Journal

Dust polarization observational results are analyzed for the high-mass star formation region W51 from the largest parent cloud ({approx}2 pc, James Clerk Maxwell Telescope) to the large-scale envelope ({approx}0.5 pc, BIMA array) down to the collapsing core e2 ({approx}60 mpc, Submillimeter Array). Magnetic field and dust emission gradient orientations reveal a correlation which becomes increasingly more tight with higher resolution. The previously developed polarization-intensity-gradient method is applied in order to quantify the magnetic field significance. This technique provides a way to estimate the local magnetic field force compared to gravity without the need of any mass or field strength measurements,more »« less

Self-consistent calculations of alpha-decay energies

Journal Article Tolokonnikov, S. V. ; Lutostansky, Yu. S. ; Saperstein, E. E., E-mail: saper@mbslab.kiae.ru - Physics of Atomic Nuclei

On the basis of the self-consistent theory of finite Fermi systems, the energies of alphadecay chains were calculated for several new superheavy nuclei discovered recently in experiments of the Dubna-Livermore Collaboration headed by Yu.Ts. Oganessian. The approach in question is implemented on the basis of the generalized method of the density functional proposed by Fayans and his coauthors. The version used here relies on the functional DF3-a proposed recently for describing a wide array of nuclear data, including data on superheavy nuclei. A detailed comparison of the results obtained on this basis with the predictions of different approaches, including themore »« less

Self-consistent calculations of the strength function and radiative neutron capture cross section for stable and unstable tin isotopes

Journal Article Avdeenkov, A. ; Goriely, S. ; Kamerdzhiev, S. ; ... - Physical Review. C, Nuclear Physics

The E1 strength function for 15 stable and unstable Sn even-even isotopes from A=100 to A=176 are calculated using a self-consistent microscopic theory which, in addition to the standard (quasiparticle) random-phase approximation [(Q)RPA] approach, takes into account phonon coupling and the single-particle continuum (by means of the discretization procedure) with a cutoff of 100 MeV. Our analysis shows two distinct regions for which the integral characteristics of both the giant and pygmy resonances behave rather differently. For neutron-rich nuclei, starting from {sup 132}Sn, we obtain a giant E1 resonance which significantly deviates from the widely used systematics extrapolated from experimentalmore »« less

Adiabatic fusion barriers from self-consistent calculations

Journal Article Skalski, J. - Physical Review. C, Nuclear Physics

Adiabatic fusion barriers are studied within the static Hartree-Fock method with the effective Skyrme interactions SkM* and SLy6. The problem of kinetic energy of the relative motion becoming spurious for separate fragments, relevant for both fusion and fission barriers, is discussed in some detail. Also discussed are the specific assumptions necessary to compensate for the nonuniqueness of the static method. Barriers obtained with two forces agree to within 2 MeV and seem nearly decoupled from errors in binding energies, specific to each force. For a number of reactions, comparisons are made with experimental estimates of barriers and barriers calculated withmore »« less
