    Notizen: Summary Fifteen xenograft tumour lines (4 osteosarcomas and 11 squamous carcinomas) were established on nude mice in numerous passages. Over a period of 4 years, samples were taken and studied systematically in more than 4000 histological slides. Of the tumour lines, 12 (4 osteosarcomas and 8 squamous carcinomas) showed remarkable dedifferentiation, but also redifferentiation towards a higher grade. There was a correlation between the rate of tumour takes in mice and poor prognosis in patients, but none between tumour doubling time and the phases of the cell cycle. Altogether, the results showed a great heterogeneity of human xenotransplants in terms of biological behaviour and morphological changes.

    Energy of the 5− isomer and (πg 9/2⊗vg 9/2) states in82Rb (1991)

    Notizen: Abstract Excited states in the doubly-odd nucleus82Rb have been investigated via the reactions79Br(α,n) and78Se(7Li,3n) using in-beamγ-ray spectroscopy. The level energy of the longlived 5− isomer has been determined to 68.3 keV which is below the energy of the 2− state found at 88.9 keV with a lifetime ofΤ=2.4(2) ns. A sequence of positive-parity states beginning with a 6+ level at 191.3 keV (Τ=20(3) ns) and extending to a (10+) level has been interpreted to contain the two-particle configuration (πg 9/2⊗Ν 9/2) and collective excitations.
