E. Sahin et al.; 9 pags.; 8 figs.; 2 tabs.; PACS number(s): 21.10.Tg, 21.60.Cs, 23.20.Lv ; © 2015 American Physical Society. The level structure of the neutron-rich 69Cu,71Cu, and Cu73 isotopes has been investigated by means of multinucleon transfer reactions. The experiment was performed at Laboratori Nazionali di Legnaro using the AGATA Demonstrator array coupled to the PRISMA magnetic spectrometer. Lifetimes of excited states in Cu nuclei were measured with the recoil-distance Doppler-shift method. The resulting electromagnetic matrix elements for transitions from excited states in Cu69,71,73 nuclei are used to assess the collective or single-particle character of these states. The results are compared with predictions of large-scale shell-model calculations, giving further insight into the evolution of the proton pf shell as neutrons fill the 1g9/2 orbital. ; This work has been partially supported by the European Union Seventh Framework Program FP7/2007-2013 under Grant Agreement No. 262010, ENSAR and MINECO, Spain, under Grants No. FPA2011-29854-C03 and No. FPA2011- 29854-C04, Generalitat Valenciana, Spain, under Grant No. PROMETEOII/2014/019, and MINECO, Spain, under Grant Consolider-Ingenio 2010 CSD2007-00042. ; Peer Reviewed

The strength functions of the π f5/2, π p3/2 and π f7/2 orbitals in neutron-rich 71Cu were obtained in a 72Zn(d,3He)71Cu proton pick-up reaction in inverse kinematics using a radioactive beam of 72Zn at 38 MeV/u. A dedicated set-up was developed to overcome the experimental challenges posed by the low cross section of the reaction and the low energy of the outgoing 3He particles. The excitationenergy spectrum was reconstructed and spectroscopic factors were obtained after analysis of the angular distributions with the finite-range Distorted-Wave Born Approximation (DWBA). The results show that unlike for the π f5/2 orbital and contrary to earlier interpretation, the π f7/2 single-particle strength distribution is not appreciably affected by the addition of neutrons beyond N = 40 ; The authors are thankful to the Ganil accelerator staff, informatics service and to the IPN design office.

5 pags., 6 figs. ; Single-neutron states in the , isotope 79Zn have been populated using the 78Zn(d, p)79Zn transfer reaction at REX-ISOLDE, CERN. The experimental setup allowed the combined detection of protons ejected in the reaction, and of γ rays emitted by 79Zn. The analysis reveals that the lowest excited states populated in the reaction lie at approximately 1 MeV of excitation, and involve neutron orbits above the shell gap. From the analysis of γ-ray data and of proton angular distributions, characteristic of the amount of angular momentum transferred, a configuration was assigned to a state at 983 keV. Comparison with large-scale-shell-model calculations supports a robust neutron shell-closure for 78Ni. These data constitute an important step towards the understanding of the magicity of 78Ni and of the structure of nuclei in the region. ; This work was supported by the European Commission through the Marie Curie Actions Contracts Nos.

9 pags., 3 figs. ; The low-lying level structure of V63 was studied for the first time by the inelastic proton scattering and the proton knock-out reaction in inverse kinematics. The comparison of the newly observed γ-ray transitions at 696(8) keV and 889(16) keV with our shell-model calculations using the Lenzi-Nowacki-Poves-Sieja interaction established two excited states proposed to be the first 11/2- and 9/2- levels. The (p,p′) excitation cross sections were analyzed by the coupled channel formalism assuming pure quadrupole as well as quadrupole+hexadecapole deformations. This resulted in large deformation parameters placing V63 in the island of inversion located below Ni68. ; We are very grateful to the RIKEN Nishina Center accelerator staff for providing the stable beam and to the BigRIPS team for the smooth operation of the secondary beams.
