    Description / Table of Contents: Zusammenfassung Ausgehend von den Allyl- und Pent-4-enyl-β-D-glucopyranosiden4–7 können dieD-Glucosederivate8–15 dargestellt werden, welche am anomeren Zentrum unterschiedlich lange Spacereinheiten mit verschiedenen Endgruppen besitzen. Bei Reaktion von vier Äquivalenten des Caesiumsalzes von Propan-4-carboxy-1-yl-2,3,4,6-tetra-O-acetyl-β-D-glucopyranosid15 mit Pentaerythrityltetrabromid entsteht das tetravalente Molekül16.
    Notes: Summary Starting with allyl- and pent-4-enyl-β-D-glucopyranosides4–7, differentD-Glucose units (8–15) containing alkyl spacers of variable lenght and with different end groups can be prepared. Reaction of four equivalents of the caesium salt derived from propan-4-carboxy-1-yl-2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside15 with pentaerythrityltetrabromide yields the tetravalent molecule16.

    Notes: Abstract The A dependence of nuclear fission induced by stopped antiprotons has been measured. An unambiguous identification of the binary fission decay mode was provided by a coordinate measurement of complementary fission fragments in coincidence using a large-acceptance fission detector based on low pressure multiwire proportional chambers. A deep fissility minimum was observed nearA=100, in agreement with the general behaviour predicted by the liquid-drop model. An unexpectedly low and high fission probability was found for the Ag and Cu nuclei, respectively.
