    Notes: [Auszug] IN a previous letter to this journal1 we have described a method of producing a steady stream of swift protons of energies up to 600 kilovolts by the application of high potentials, and have described experiments to measure the range of travel of these protons outside the tube. ...

    Notes: [Auszug] CURIE and Joliot1 have reported that a number of new radioactive isotopes can be produced by the bombardment of various elements with α-particles, these isotopes emitting positive electrons. In particular, they showed that boron when bombarded by α-particles was transformed to ...

    Notes: [Auszug] SINCE the publication of our paper1 on the disintegration of elements by fast protons, we have examined some of the light elements more carefully, using much thinner mica windows than we had previously employed on the high voltage tube. With the present arrangement, we can count ...

    Description / Table of Contents: Thorium Bromide Clusters with Octahedral Th6 UnitsThe preparation, structures and properties of the compounds MTh6Br15 (M = Mn, Fe, Co, Ni), NaxFeTh6Br15, Th6Br15H7 and Th6Br14C are described (MTh6Br15: Im3m; M = Mn: a = 1150.85(3) pm; Fe: a = 1148.81(4) pm; Co: a = 1150.68(2) pm; Ni: a = 1151.43(4) pm; Th6Br15H7: a = 1140.7(1) pm; Th6Br14C: Cmca; a = 1576.4(3) pm, b = 1416.0(4) pm; c = 1312.4(3) pm). The structures of these compounds are closely related to those of the niobium halides Nb6F15 and Nb6Cl14, respectively. All compounds contain Th6Br12 clusters with octahedral Th6 cores and interstitial atoms in these cores. The magnetic properties of the compounds are discussed and compared with the results of Extended-Hückel calculations.
    Notes: Die Darstellung, Strukturen und Eigenschaften der Verbindungen MTh6Br15 (M=Mn, Fe, Co, Ni), NaxFeTh6Br15, Th6Br15H7 und Th6Br14C werden beschrieben. Die Strukturen dieser Verbindungen leiten sich von denen der bekannten Niobhalogenide Nb6F15 und Nb6Cl14 ab (MTh6Br15: Im3m; M = Mn: a = 1150,85(3) pm; Fe: a = 1148,81(4) pm; Co: a = 1150,68(2) pm; Ni: a = 1151,43(4) pm; Th6Br15H7: a = 1140,7(1) pm; Th6Br14C: Cmca; a = 1576,4(3) pm; b = 1416,0(4) pm; c = 1312,4(3) pm). Alle Verbindungen enthalten Th6Br12-Cluster mit oktaedrischen Th6-Einheiten und interstitiellen Atomen im Oktaeder. Die magnetischen Eigenschaften der Verbindungen werden beschrieben und anhand von Extended-Hückel-Rechnungen diskutiert.
