Title: Impact of shell structure on the fusion of neutron-rich mid-mass nuclei

Abstract

The influence of shell effects on fusion of mid-mass nuclei is explored using isotopic chains of K and Ar ions on an oxygen target. Comparison of the reduced excitation functions reveals that the fusion cross section for the open neutron-shell projectile nuclei ⁴¹K and ⁴⁵K is systematically larger than for the closed neutron-shell projectiles ³⁹K and ⁴⁷K. Furthermore, the São Paulo fusion model using matter densities from systematics fails to describe the measured excitation functions. Use of more realistic densities from a Dirac-Hartree-Bogoliubov (DHB) approach performs significantly better though it still overpredicts the closed-shell nuclei.

Proton and neutron exchange as a prelude to fusion at near-barrier energies

Journal Article Johnstone, J. E. ; Singh, Varinderjit ; Giri, R. ; ... - Physical Review. C

Systematic examination of fusion for ^39,41,45,47K + ²⁸Si and ^36,44Ar + ²⁸Si provides insight into the impact of neutron and proton exchange on fusion for nuclei at and near the N = 20 and N = 28 shells. Comparison of the reduced excitation functions reveals a marked difference between the behavior of open-shell and closed-shell systems. While coupled channels calculations provide a good description for the closed-shell nuclei, they significantly underpredict the fusion cross section for open-shell nuclei. Furthermore, the observed trends are examined in the context of a potential energy surface, including shell effects, and multinucleon exchange with considerationmore » of Pauli blocking.« less

Laser Spectroscopy of Neutron-Rich ${}^{207, 208}{Hg}$ Isotopes: Illuminating the Kink and Odd-Even Staggering in Charge Radii across the $N = 126$ Shell Closure

Journal Article Day Goodacre, T. ; Afanasjev, A. V. ; Barzakh, A. E. ; ... - Physical Review Letters

The mean-square charge radii of ^207,208Hg (Z = 80, N = 127,128) have been studied for the first time and those of ^202,203,206Hg (N = 122,123,126) remeasured by the application of in-source resonance ionization laser spectroscopy at ISOLDE (CERN). The characteristic kink in the charge radii at the N = 126 neutron shell closure has been revealed, providing the first information on its behavior below the Z = 82 proton shell closure. A theoretical analysis has been performed within relativistic Hartree-Bogoliubov and nonrelativistic Hartree-Fock-Bogoliubov approaches, considering both the new mercury results and existing lead data.

Nuclear energy density optimization: Shell structure

Journal Article Kortelainen, M. ; McDonnell, J. ; Nazarewicz, W. ; ... - Physical Review. C. Nuclear Physics

Nuclear density functional theory is the only microscopical theory that can be applied throughout the entire nuclear landscape. Its key ingredient is the energy density functional. Here, we propose a new parametrization UNEDF2 of the Skyrme energy density functional. The functional optimization is carried out using the POUNDERS optimization algorithm within the framework of the Skyrme Hartree-Fock-Bogoliubov theory. Compared to the previous parametrization UNEDF1, restrictions on the tensor term of the energy density have been lifted, yielding a very general form of the energy density functional up to second order in derivatives of the one-body density matrix. In order tomore »« less

Ab initio Bogoliubov coupled cluster theory for open-shell nuclei

Journal Article Signoracci, Angelo J. ; Duguet, Thomas ; Hagen, Gaute ; ... - Physical Review C

Background: Ab initio many-body methods have been developed over the past 10 yr to address closed-shell nuclei up to mass A≈130 on the basis of realistic two- and three-nucleon interactions. A current frontier relates to the extension of those many-body methods to the description of open-shell nuclei. Several routes to address open-shell nuclei are currently under investigation, including ideas that exploit spontaneous symmetry breaking. Purpose: Singly open-shell nuclei can be efficiently described via the sole breaking of U(1) gauge symmetry associated with particle-number conservation as a way to account for their superfluid character. While this route was recently followed withinmore »« less

Shell-model states with seniority $ν = 3$ , 5, and 7 in odd- $A$ neutron-rich Sn isotopes

Journal Article Iskra, Ł. W. ; Broda, R. ; Janssens, R. V. F. ; ... - Physical Review C

Excited states with seniority ν=3, 5, and 7 have been investigated in odd neutron-rich Sn119,121,123,125 isotopes produced by fusion-fission of 6.9-MeV/ACa48 beams with Pb208 and U238 targets and by fission of a U238 target bombarded with 6.7-MeV/ANi64 beams. Level schemes have been established up to high spin and excitation energies in excess of 6 MeV, based on multifold gamma-ray coincidence relationships measured with the Gammasphere array. In the analysis, the presence of isomers was exploited to identify gamma rays and propose transition placements using prompt and delayed coincidence techniques. Gamma decays of the known 27/2- isomers were expanded by identifyingmore »« less
