    Description / Table of Contents: Zusammenfassung Unter 600 tödlichen Verkehrsunfällen beobachteten wir Schädelbasiscondylenverletzungen bei 10 Zweiradfahrern, 12 Pkw-Fahrern und 3 Fußgängern. Die Kollisionsgeschwindigkeiten lagen meistens zwischen 70–100 km/h. In 18 Fällen mit direktem Kopfanstoß lag die schwerere Verletzung häufig auf der Gegenseite, beim indirekten Seitenanstoß (Schleudertrauma) auf der gleichen Seite. Häufigste Bruchformen waren 12mal horizontale Abtrennungen und 4mal Innenkantenabbrüche. 9mal waren die Condylenverletzungen einseitig, 16mal beidseitig lokalisiert.
    Notes: Summary Among 600 deads of traffic accidents we found injuries of the occipital condyles in 10 cyclists, 12 car drivers and 3 pedestrians. In most cases the collision speed ranged from 70 to 100 km/h. In 18 cases of direct head impact the more severe injury was on the opposite side, in 4 cases of indirect side impact (whiplash injury) on the same side. Most types of fractures were 12 horizontal disconnections and 4 fractures of the inner edges. In 9 cases the condyle fractures were on one side, in 16 cases on both sides.

    Notes: Abstract Double-differential emission probabilities P (E, θ) in angle θ and energy E of protons, tritons, and α-particles were measured in the case of spontaneous fission of252Cf. A detector system consisting of position-sensitive parallel-plate avalanche counters (PPAC) and ΔE−E-telescopes allowed a coincidence measurement of fission fragments (FF) and light charged particles (LCP) in the whole region from 0 deg. to 180 deg. with respect to the light-fragment direction. Previous results for α-particle emission were confirmed. The background contributions for protons are discussed in detail. For proton emission the background arising from (n, p)-reactions was measured and compared with a corresponding Monte-Carlo simulation of elastic (n, p)-clusions. Unlike for tritons and a-particles the P (E, θ) distribution for protons does not show equatorial peaking in 0 between 80 deg. and 90 deg. and contradicts classical scission point emission. The proton distribution, however, agrees with fragment de-excitation calculations in the framework of the cascade evaporation model (CEM) whereas an analogous calculation forα-particles completely fails. Upper limits for an additional scission component of proton emission are given.

    Notes: Abstract Emission distributions P(E,θ) in energy E and angle θ of protons (p), tritons (t), and ∝-particles released in spontaneous fission of 252-Cf have been measured. Whereas the experimental data for t and ∝ indicate the expected tripartition as the predominant mode, p emission has been found to be due to fragment de-excitation from highly excited, rapidly moving fragments mainly.

    Description / Table of Contents: Contributions on the Thermal Behaviour of Anhydrous Phosphates. VII Preparation, Structure, and Thermal Behaviour of Orthorhombic NbPO5-δBy a chemical vapour transport in a temperature gradient (e.g. 1000° → 9000°C) it is possible to prepare the already known forms of NbPO5 and a new phase as single crystals. Using I2 or NH4Cl as transport agents α-NbPO5 was obtained as colourless crystals, which enabled a refinement of the already known tetragonal crystal structure to R = 1.73%. The dark blue crystals of the up to now unknown orthorhombic phase could only be prepared under reducing conditions (by adding NbP). Their crystall structure is related to monoclinic β-NbPO5 (single crystall investigation, space group Pna21; a = 11.2875 Å; b = 6.6296 Å; c = 5.2871 Å; Z = 4; R = 3.17%), but the crystals are deficient in oxygen according to NbPO5-δ recognizable by the dark blue colour. When NbPO5-δ (orthorhombic) is ground in an agate mortar NbPO5-δ (monoclinic) is formed, which has the already known structure of β-NbPO5. By heating (340°C) a reversible transformation from NbPO5-δ (monoclinic) to NbPO5-δ (orthorhombic) takes place. This is isostructural to WPO5 and also to an orthorhombic modification of (colourless) NbPO5, which we also could observe above 340°C.
    Notes: Über einen chemischen Transport im Temperaturgefälle (z. B. 1000° → 900° C) gelingt die Darstellung der beiden bekannten Formen von NbPO5 sowie einer weiteren neuen Phase in einkristalliner Form. α-NbPO5 wurde mit den Transportmitteln I2 oder NH4Cl in farblosen Kristallen erhalten, die eine Verfeinerung der bekannten tetragonalen Kristallstrukur bis zu R = 1,73% ermöglichten. Die dunkelblauen Kristalle der bislang unbekannten orthorhombischen Phase konnten nur unter reduzierenden Bedingungen (Zusatz von NbP) dargestellt werden. Sie haben einen mit monoklinem β-NbPO5 eng verwandten Aufbau (Einkristalluntersuchungen; R. G. Pna21; a = 11,2875 Å; b = 6,6296 Å; c = 5,2871 Å; z = 4; R = 3,17%), weisen aber ein ihrer dunklen Farbe erkennbares Sauerstoffdefizit gemäß NbPO5-δ auf. Durch Zerreiben von NbPO5-δ (orthorh.) erhält man NbPO5-δ (mon.), das die bekannte Struktur von β-NbPO5 besitzt und beim Aufheizen (340°C) reversibel in die orthorhombische Phase NbPO5-δ übergeht. Diese ist isostrukturell mit WPO5 sowie mit einer orthorhombischen Modifikation von (farblosem) NbPO5, die wir ebenfalls oberhalb 340°C beobachten konnten.
