    Monocyte recruitment into the scrapie-affected brain (1995)

    Notes: Abstract The recruitment of monocytes into the scrapie-affected brain was investigated in female mice reconstituted with male bone marrow, using a Y-chromosome-specific probe and F4/80 immunocytochemistry. Recruitment of monocytes could be demonstrated in six out of eight animals and the number of recruited cells correlated with the severity of vacuolation in most, but not all, animals. The proportion of microglia derived from recruited monocytes varied between individual animals, did not correlate with the increase in cellularity (glia) in affected areas of brain and did not affect the length of incubation period. Thus, it is unlikely that the recruitment of monocytes is a pivotal event in the development of early pathological changes in scrapie. The morphology of recruited cells in scrapie lesions, as revealed by F4/80 immunoreactivity, was indistinguishable from that of activated resident microglia.

    Thermal neutron captureγ-ray spectroscopy of59Ni and61Ni (1993)
    Springer
    The European physical journal 345 (1993), S. 143-153 
    Details
    ISSN: 1434-601X
    Keywords: 21.10.Ma ; 23.20.Lv ; 25.40.Lw ; 27.50.+ e

    Notes: Abstract Theγ-radiation emitted after thermal neutron capture in isotopically enriched58Ni and60Ni was measured at the ILL high flux reactor by means of Ge/NaI detectors operated in Compton suppression and pair spectrometer mode. The neutron binding energies were determined asB n (59Ni)=8999.15(23) keV and Bn(61Ni)=7820.07(20) keV; some 95% of the totalγ-ray fluxes through59,61Ni were assigned. Theγ-ray strength functions of the primary transitions and the level densities are discussed.

    Double neutron capture in62Ni (1992)
    Springer
    The European physical journal 343 (1992), S. 7-14

    Notes: Abstract The γ-radiation following single and double neutron capture in isotopically enriched62Ni was studied at the high flux reactor of the Institut Laue-Langevin, using a pair and Compton suppressed germanium detector. Measurements before and after 170 d of breeding were performed. The γ-ray fluxes through63Ni and64Ni are discussed; several new levels and spin-parity assignments were found. On the basis of the known discrete levels and the low-energy neutron resonances, level density parameters were determined within the Constant Temperature Fermi Gas model. The neutron binding energies were measured asB n (63Ni)=6837.92(18) keV andB n (64Ni)=9657.64(24) keV. The63Ni (n, γ) cross section for reactor neutrons was measured to be σ=20 −2 +5 b.
