    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.

    Absolute pionic x-ray intensities in Mg and Fe (1991)
    Springer
    The European physical journal 341 (1991), S. 101-105

    Notes: Abstract Absolute pionic x-ray intensities have been measured for Mg and Fe. The accuracy achieved was 2% of the line intensity for the most prominent transitions. In the Balmer series of Mg and the Paschen series of Fe the crossover transitions were found to be even more attenuated than the transitions between circular states, as deduced, for example, by comparison with muonic atoms; no crossover transitions were observed in the Fe Balmer series. According to cascade calculations based on the experimental intensities more than half of the pions are absorbed in Fe already from levels with principal quantum numbern〉17 by strong interaction.

    Notes: Abstract The yields of the atomic 4→3 transitions in antiprotonic14N,16,17,18O,19F, and23Na were measured at the CERN antiproton facility, LEAR. From these, the widths Γup of the 4f levels were determined to be 136±19meV (14N); 603±22 meV (16O); 731±35 meV (17O); 795±23 meV (18O); 2.79±0.16 eV (19F); and 23.8±7.4 eV (23Na).

    First direct observation of strong interaction spin-orbit effects in antiprotonic atoms (1988)

    Notes: Abstract The strong ¯p-nucleus spin-orbit interaction was investigated in a measurement of the strong-interaction effects of the 9→8 transition in ¯p 174Yb at the Low-Energy Antiproton Ring (LEAR) at CERN. This measurement was part of an experimental programme where, for the first time, the fine-structure components of the last observable X-ray transition in a ¯p atom, which carries information on the strong ¯p-nucleus interaction, were resolved and studied individually. The observed splitting ΔE exp=2408±26 eV consists of the electromagnetic fine-structure splitting ΔE FS=2350 eV and an additional splitting Δɛ=58±26 eV. In addition, one finds a significant difference in the level widths of Δ=195±59 eV with the larger value⇊=1216±41 eV for the lower fine-structure level. This experiment follows an earlier measurement on ¯p 138Ba, where the transition 8→7 is influenced by the strong interaction. In this case, however, the fine-structure components could not be resolved. The results for174Yb may be attributed to a spin-orbit (LS) term in the complex strong-interaction potential.

    On spline collocation methods for boundary integral equations in the plane (1985)

    Notes: Nowadays boundary elemen; methods belong to the most popular numerical methods for solving elliptic boundary value problems. They consist in the reduction of the problem to equivalent integral equations (or certain generalizations) on the boundary Γ of the given domain and the approximate solution of these boundary equations. For the numerical treatment the boundary surface is decomposed into a finite number of segments and the unknown functions are approximated by corresponding finite elements and usually determined by collocation and Galerkin procedures. One finds the least difficulties in the theoretical foundation of the convergence of Galerkin methods for certain classes of equations, whereas the convergence of collocation methods, which are mostly used in numerical computations, has yet been proved only for special equations and methods.In the present paper we analyse spline collocation methods on uniform meshes with variable collocation points for one-dimensional pseudodifferential equations on a closed curve with convolutional principal parts, which encompass many classes of boundary integral equations in the plane. We give necessary and sufficient conditions for convergence and prove asymptotic error estimates. In particular we generalize some results on nodal and midpoint collocation obtained in [2], [7] and [8].The paper is organized as follows. In Section 1 we formulate the problems and the results, Section 2 deals with spline interpolation in periodic Sobolev spaces, and in Section 3 we prove the convergence theorems for the considered collocation methods.
