Title: Cluster Structures, Halos, Skins, and S-Factors in Fermionic Molecular Dynamics

Abstract

Light nuclei are studied in the Fermionic Molecular Dynamics model. No a priori assumptions are made with respect to cluster structure or single-particle energies. The same effective interaction based on the Argonne V18 interaction is used for all nuclei. Short-range central and tensor correlations are treated explicitly using a unitary correlation operator. Calculations of binding energies and radii for Helium and Carbon isotopes are presented. The evolution of cluster structures and halos with increasing neutron number is discussed. The spectrum of 12C is calculated in a multiconfiguration calculation. The molecular structure of the excited states is investigated. The astrophysical S-factors are calculated for the fusion of different Oxygen isotopes.

  • The reaction of tetraphosphorus trisulfide or tetraphosphorus triselenide with (MCl(cod))/sub 2/ (M = Rh, Ir; cod = cycloocta-1,5-diene) in the presence of triphos (triphos = 1,1,1-tris((diphenylphosphino)methyl)ethane, CH/sub 3/C(CH/sub 2/PPh/sub 3/)/sub 3/) yields the compounds ((triphos)M(P/sub 3/X/sub 3/)) x C/sub 6/H/sub 6/ (M = Rh, X = S (1), Se (2); M = Ir, X = S (3), Se (4)). The crystal structures of 1-3 have been elucidated through complete x-ray analyses. The compounds crystallize in the orthorhombic P2/sub 1/nb space group with Z = 4 and the following unit-cell dimensions: 1, a = 19.109 (5) /angstrom/, b = 19.445 (5)more » /angstrom/, c = 12.319 (4) /angstrom/; 2, a = 19.277 (7) /angstrom/, b = 19.608 (9) /angstrom/, c = 12.398 (6) /angstrom/; 3, a = 19.131 (9) /angstrom/, b = 19.451 (9) /angstrom/, c = 12.293 (6) /angstrom/.

  • Density functional theory (DFT) Born-Oppenheimer molecular dynamics (BOMD) simulations of metal clusters are presented. The calculations have been performed with the deMon2k [1] code employing all-electron basis sets and local and non-local functionals. The capability to perform reasonable long (∼ 100 ps) first-principle BOMD simulations in order to explore potential energy landscape of metallic clusters will be presented [2,3]. The evolution of the cluster structures and properties, such as polarizability and heat capacity, with temperature is discussed.
  • Radioactive beam experiments have made it possible to study, the properties of nuclei far from the beta-stability line. The most detailed studies have been performed with light neutron-rich nuclei. The weak binding allows the valence neutrons to form an extended density tail, a so-called neutron halo or skin. It also permits a new low-lying mode of electric dipole excitation associated with the relative motion of the valence neutrons and the core. The principal experimental evidence for these features is unusually large breakup cross sections. Another characteristic feature is that nuclei which are at the edge of the neutron drip linemore » contain an even number of neutrons whereas neighboring odd-N isotopes are often particle unstable. This implies that pair interactions between the valence neutrons play a crucial role for the binding. Examples of nuclei that exhibit all of these features, and which have been studied in the greatest detail, are {sup 6}He, {sup 11}Li and {sup 14}Be. The neutron skin or halos consist in these cases of two valence neutrons interacting with a more tightly bound core. This makes them suitable for theoretical studies in terms of three-body models. An example of a nucleus which contains a single-neutron halo is {sup 11}Be. It has also been studied in breakup reactions, and its structure is of particular interest because of the ground-state parity inversion, which has been a theoretical problem for many years. The status and interpretations of experimental and theoretical studies of nuclei close to the neutron drip line will be reviewed.« less
  • Nuclei with large neutron-to-proton ratios have neutron skins, which manifest themselves in an excess of neutrons at distances greater than the radius of the proton distribution. In addition, some drip-line nuclei develop very extended halo structures. The neutron halo is a threshold effect; it appears when the valence neutrons occupy weakly bound orbits. In this study, nuclear skins and halos are analyzed within the self-consistent Skyrme-Hartree-Fock-Bogoliubov and relativistic Hartree-Bogoliubov theories for spherical shapes. It is demonstrated that skins, halos, and surface thickness can be analyzed in a model-independent way in terms of nucleonic density form factors. Such an analysis allowsmore » for defining a quantitative measure of the halo size. The systematic behavior of skins, halos, and surface thickness in even-even nuclei is discussed.
