  Title On the enhanced E1 transitions in the K=3/2 parity doublet band in Ra-223 Type Journal Article
  Year 2016 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A  
  Volume 52 Issue 6 Pages 172 - 10pp  
  Keywords  
  Abstract We have applied the fast timing beta gamma gamma(t) technique to remeasure lifetimes of selected states in Ra-223 populated in the beta(-) decay of Fr-223. T-1/2 = 587(12) ps and 210(13) ps have been obtained for the 3/2(-) and 5/2(-) states at 50.1 and 79.7 keV, that are more accurate than the previous values of 630(70) ps and 166(55) ps, respectively. Our vertical bar D0 vertical bar value of 0.155(10) e.fm obtained for the K = 3/2 configuration together with the available values of vertical bar D0 vertical bar for the K = 1/2 and K = 5/2 parity doublet bands establish the configuration dependence of vertical bar D0 vertical bar at low spins in this nucleus. Results of theoretical calculations performed for Ra-223, using the quasiparticle-phonon model (QPM) with inclusion of the Coriolis coupling, reasonably well reproduce octupole correlations in this nucleus.

  Title Search for two-phonon octupole excitations in Gd-146 Type Journal Article
  Year 2016 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A  
  Volume 52 Issue 6 Pages 166 - 7pp  
  Keywords  
  Abstract The low-spin structure of the nearly spherical nucleus Gd-146 was studied using the Sm-144(He-4, 2n) fusion-evaporation reaction. High-statistics gamma-gamma coincidence measurements were performed at iThemba LABS with 7x10(9) gamma-gamma coincidence events recorded. Gated gamma-ray energy spectra show evidence for the 6(2)(+) -> 3(1)(-) -> 0(1)(+) cascade of E3 transitions in agreement with recent findings by Caballero and co-workers, but with a smaller branching ratio of I-gamma = 4.7(10) for the 6(2)(+) -> 3(1)(-) 1905.1 keV gamma ray. Although these findings may support octupole vibrations in spherical nuclei, sophisticated beyond mean-field calculations including angular-momentum projection are required to interpret in an appropriate way the available data due to the failure of the rotational model assumptions in this nucleus.

  Title Proton-hole and core-excited states in the semi-magic nucleus In-131(82) Type Journal Article
  Year 2016 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A  
  Volume 52 Issue 11 Pages 347 - 10pp  
  Keywords  
  Abstract The decay of the N = 83 nucleus Cd-131 has been studied at the RIBF facility at the RIKEN Nishina Center. The main purpose of the study was to identify the position of the and proton-hole states and the energies of core-excited configurations in the semi-magic nucleus In-131. From the radiation emitted following the decay, a level scheme of In-131 was established and the feeding to each excited state determined. Similarities between the single-particle transitions observed in the decays of the N = 83 isotones In-132 and Cd-131 are discussed. Finally the excitation energies of several core-excited configurations in In-131 are compared to QRPA and shell-model calculations.

  Title Remarks on the P-c structures and triangle singularities Type Journal Article
  Year 2016 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A  
  Volume 52 Issue 10 Pages 318 - 6pp  
  Keywords  
  Abstract It was proposed that the narrow P-c(4450) structure observed by the LHCb Collaboration in the reaction Lambda(b) -> J/psi pK might be due to a triangle singularity around the chi(c1)-proton threshold at 4.45 GeV. We discuss the occurrence of a similar triangle singularity in the J/psi p invariant mass distribution for the decay Lambda(b) -> J/psi p pi, which could explain the bump around 4.45 GeV in the data. More precise measurements of this process would provide valuable information towards an understanding of the P-c structures.

  Title Feasibility studies of time-like proton electromagnetic form factors at PANDA at FAIR Type Journal Article
  Year 2016 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A  
  Volume 52 Issue 10 Pages 325 - 23pp  
  Keywords  
  Abstract Simulation results for future measurements of electromagnetic proton form factors at PANDA (FAIR) within the PandaRoot software framework are reported. The statistical precision with which the proton form factors can be determined is estimated. The signal channel (p) over barp -> e(+)e(-) is studied on the basis of two different but consistent procedures. The suppression of the main background channel, i.e. (p) over barp -> pi(+)pi(-), is studied. Furthermore, the background versus signal efficiency, statistical and systematical uncertainties on the extracted proton form factors are evaluated using two different procedures. The results are consistent with those of a previous simulation study using an older, simplified framework. However, a slightly better precision is achieved in the PandaRoot study in a large range of momentum transfer, assuming the nominal beam conditions and detector performance.

  Title Prospects for direct neutron capture measurements on s-process branching point isotopes Type Journal Article
  Year 2017 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A  
  Volume 53 Issue 5 Pages 87 - 5pp  
  Keywords  
  Abstract The neutron capture cross sections of several unstable key isotopes acting as branching points in the s-process are crucial for stellar nucleosynthesis studies, but they are very challenging to measure directly due to the difficult production of sufficient sample material, the high activity of the resulting samples, and the actual (n, gamma) measurement, where high neutron fluxes and effective background rejection capabilities are required. At present there are about 21 relevant s-process branching point isotopes whose cross section could not be measured yet over the neutron energy range of interest for astrophysics. However, the situation is changing with some very recent developments and upcoming technologies. This work introduces three techniques that will change the current paradigm in the field: the use of gamma-ray imaging techniques in (n,gamma) experiments, the production of moderated neutron beams using high-power lasers, and double capture experiments in Maxwellian neutron beams.

  Title Half-life determination of T-z =-1 and T-z =-1/2 proton-rich nuclei and the beta decay of Zn-58 Type Journal Article
  Year 2017 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A  
  Volume 53 Issue 6 Pages 134 - 10pp  
  Keywords  
  Abstract We have measured the beta-decay half-lives of 16 neutron-deficient nuclei with T-z = -1/2 and -1, ranging from chromium to germanium. They were produced in an experiment carried out at GANIL and optimized for the production of Zn-58, for which in addition we present the decay scheme and absolute Fermi and Gamow-Teller transition strengths. Since all of these nuclei lie on the rp-process pathway, the T-1/2 values are important ingredients for the rp-process reaction flow calculations and for models of X-ray bursters.

  Title Stretched configuration of states as inferred from gamma-ray angular distributions in Ar-40+Pb-208 neutron transfer reactions Type Journal Article
  Year 2017 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A  
  Volume 53 Issue 8 Pages 166 - 6pp  
  Keywords  
  Abstract Angular distributions of.-rays for selected transitions in Ar-40,Ar-41,Ar-42 isotopes have been studied with the PRISMA magnetic spectrometer coupled to the CLARA gamma array. These transitions were populated in Ar isotopes reached via neutron transfer in the Ar-40 + Pb-208 reaction. By comparison with the shape of the experimental angular distribution of the known E2 transitions we established more firmly the spin and parity of excited states. In particular, in Ar-41 for the (11/2(-)) state through the (11/2(-)) -> 7/2(-) transition whose structure was discussed in terms of a phonon-fermion coupled state. The comparison with the expected fully aligned spin indicated that a high level of spin alignment has been reached.

  Title Prompt-delayed gamma-ray spectroscopy with AGATA, EXOGAM and VAMOS plus Type Journal Article
  Year 2017 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A  
  Volume 53 Issue 8 Pages 162 - 8pp  
  Keywords  
  Abstract A new experimental setup to measure prompt-delayed gamma-ray coincidences from isotopically identified fission fragments, over a wide time range of 100 ns-200 μs, is presented. The fission fragments were isotopically identified, on an event-by-event basis, using the VAMOS++ large acceptance spectrometer. The prompt gamma rays emitted at the target position and corresponding delayed gamma rays emitted at the focal plane of the spectrometer were detected using, respectively, thirty two crystals of the AGATA gamma-ray tracking array and seven EXOGAM HPGe Clover detectors. Fission fragments produced in fusion and transfer-induced fission reactions, using a U-238 beam at an energy of 6.2MeV/u impinging on a Be-9 target, were used to characterize and qualify the performance of the detection system.

  Title Determination of lifetimes of nuclear excited states using the Recoil Distance Doppler Shift Method in combination with magnetic spectrometers Type Journal Article
  Year 2017 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A  
  Volume 53 Issue 10 Pages 211 - 5pp  
  Keywords  
  Abstract The current work presents the determination of lifetimes of nuclear excited states using the Recoil Distance Doppler Shift Method, in combination with spectrometers for ion identification, normalizing the intensity of the peaks by the ions detected in the spectrometer as a valid technique that produces results comparable to the ones obtained by the conventional shifted-to-unsifted peak ratio method. The technique has been validated using data measured with the gamma-ray array AGATA, the PRISMA spectrometer and the Cologne plunger setup. In this paper a test performed with the AGATA-PRISMA setup at LNL and the advantages of this new approach with respect to the conventional Recoil Distance Doppler Shift Method are discussed.
