  Photoneutron cross sections were measured for 58Ni, 60Ni, 61Ni, and 64Ni at energies between the one-neutron and two-neutron thresholds using quasimonochromatic γ -ray beams produced in laser Compton scattering at the NewSUBARU synchrotron radiation facility. These photoneutron data are used to extract the γ -ray strength function above the neutron threshold, complementing the information obtained by the Oslo method below the threshold. We discuss radiative neutron-capture cross sections and the Maxwellian-averaged cross sections for Ni isotopes including 63Ni, a branching point nucleus along the weak s-process path. The cross sections are calculated with the experimentally constrained γ-ray strength functions from the Hartree-Fock-Bogolyubov plus quasiparticle–random-phase approximation based on the Gogny D1M interaction for both E1 and M1 components and supplemented with the M1 upbend.

  A new high efficiency scintillator array consisting of 30 large volume LaBr3(Ce) detectors are currently being developed at the Oslo Cyclotron Laboratory (OCL), University of Oslo. The first commissioning experiments was performed in December 2017 with 15 of the detectors installed. The array has been characterized and response functions have been extracted from in-beam particle-γ coincidences. The experimental response functions have been reproduced by Geant4 simulations modeling the full setup. The data acquisition system at OCL will be replaced by modern electronics from XIA in mid February, 2018.
