  • limits on spin dependent wimp nucleon Cross Sections from 225 live days of xenon100 data
    Physical Review Letters, 2013
    Co-Authors: E Aprile, M Alfonsi, K Arisaka, F Arneodo, C Balan, L Baudis, B Bauermeister, A Behrens, P Beltrame, K Bokeloh
    Abstract:

    We present new experimental constraints on the elastic, spin-dependent WIMP-nucleon Cross section using recent data from the XENON100 experiment, operated in the Laboratori Nazionali del Gran Sasso in Italy. An analysis of 224.6 live days×34  kg of exposure acquired during 2011 and 2012 revealed no excess signal due to axial-vector WIMP interactions with Xe129 and Xe131 nuclei. This leads to the most stringent upper limits on WIMP-Neutron Cross Sections for WIMP masses above 6  GeV/c2, with a minimum Cross section of 3.5×10−40  cm2 at a WIMP mass of 45  GeV/c2, at 90% confidence level.

  • Limits on spin-dependent WIMP-nucleon Cross-Sections from the first ZEPLIN-II data
    Physics Letters B, 2007
    Co-Authors: G.j. Alner, H.m. Araújo, A. Bewick, C. Bungau, B. Camanzi, M. J. Carson, R. J. Cashmore, H. Chagani, V. Chepel, D. Cline
    Abstract:

    The first underground data run of the ZEPLIN-II experiment has set a limit on the nuclear recoil rate in the two-phase xenon detector for direct dark matter searches. In this Letter the results from this run are converted into the limits on spin-dependent WIMP-proton and WIMP-Neutron Cross-Sections. The minimum of the curve for WIMP-Neutron Cross-section corresponds to 7×10 pb at a WIMP mass of around 65 GeV.

  • Covariance of Neutron Cross Sections for 16O through R-matrix Analysis
    Nuclear Data Sheets, 2015
    Co-Authors: Satoshi Kunieda, Toshihiko Kawano, Mark W. Paris, Gerald M. Hale, Keiichi Shibata, Tokio Fukahori
    Abstract:

    Abstract Through the R-matrix analysis, Neutron Cross Sections as well as the covariance are estimated for 16 O in the resolved resonance range. Although we consider the current results are still preliminary, we present the summary of the Cross section analysis and the results of data uncertainty/covariance, including those for the differential Cross Sections. It is found that the values obtained highlight consequences of nature in the theory as well as knowledge from measurements, which gives a realistic quantification of evaluated nuclear data covariances.

  • Evaluation of Neutron Cross Sections of Carbon-12 for Energies up to 80 MeV
    Journal of Nuclear Science and Technology, 1997
    Co-Authors: Masahide Harada, Yukinobu Watanabe, Satoshi Chiba, Tokio Fukahori
    Abstract:

    We have evaluated the Cross Sections of 12C for Neutrons up to 80MeV, paying more attention to the intermediate energy range above 20MeV. For energies below 20MeV, the evaluated data of JENDL-3.2 were adopted with some modifications. In the energy range above 20MeV, total Cross section and its covariance matrix were evaluated using a generalized least-squares method with available experimental data. The spherical optical model was used to evaluate reaction and elastic scattering Cross Sections. Inelastic scattering to the first 2+ state was calculated based on the DWBA. The optical potentials used in these calculations were obtained by means of the microscopic folding model based on the Jeukenne-Lejeune-Mahaux theory. Double-differential emission Cross Sections for Neutron, proton, deuteron, triton, 3He, alpha-particle and other heavier products were calculated using the Monte-Carlo method by which three-body simultaneous breakup process and two-body sequential decay process were taken into account in n+1...
