    Notes: Abstract The cross sections for Bhabha and Møller scattering have been investigated in the energy range 2.1–2.4 MeV using monoenergetic positrons and electrons to search for hypothetical resonances superimposed to the continuum predicted by quantum electro dynamics. Bhabba-to-Mott, Møller-to-Mott and Møller-to-Bhabha cross section ratios were measured. The Bhabha-to-Mott ratios could be determined with statistical errors of typically 1% and remaining systematic errors not exceeding the statistical ones. No resonances in Bhabha scattering were observed. Limits for the intrinsic widths of hypothetical resonances are given. For the first time upper limits are deduced from our data for hypothetical resonances in the Møller scattering cross section in the MeV range. Additionally, Møller-to-Bhabha cross section ratios could be determined with good precision. A good agreement between the experimental and theoretical Møller-to-Bhabha ratios can be stated calling in question the recently predicted existence of series of narrow, unresolvable resonances in the Bhabha scattering cross section.

    Description / Table of Contents: Zusammenfassung. Wir berichten über den Fall einer subacromialen Schulterluxation, die durch die Kombination von einer cranialen Glenoidfraktur und einer Acromionfraktur möglich wurde. Der Patient hatte sich diese ungewöhnliche Kombinationsverletzung im Rahmen eines Handballspiels zugezogen. Erst die weiterführende Diagnostik mit einem CT der Schulter zeigte das ganze Ausmaß der Verletzung. Es erfolgte die osteosynthetische Versorgung der Glenoidfraktur nach Reposition der Schulter. Das postoperative Ergebnis zeigte eine gute anatomische Rekonstruktion der glenoidalen Gelenkfläche. Der Patient hat nach Abschluß unserer Behandlung eine gute funktionelle Wiederherstellung der Beweglichkeit im Schultergelenk mit Abduktion bis 180 ° und ist wieder voll berufstätig.
    Notes: Summary. We report on a case of subacromial shoulder dislocation, which resulted from a combination of a cranial glenoid fracture and an acromial fracture. The patient sustained this rare injury while playing handball. The whole implication of the injury was revealed only after extensive workup with CT scan of the shoulder. After reduction of the shoulder dislocation, the glenoid fracture was stabilized by osteosynthesis. The postoperative results showed anatomical reconstruction of the glenoid joint surface. After completion of therapy, the patient has achieved good functional results with a full range of motion (abduction 180 °) and has been able to work full-time again.

    Notes: Abstract Strongly damped collisions were studied in uranium induced reactions on110Pd and124Sn target nuclei near the barrier. The excitation-energy splitting was deduced from binary reaction yields and those in which the heavy fragment undergoes sequential fission. For systems with 87≦Z≦95 for the heavy fragment, the excitation energy is concentrated in the lighter nucleus, at best shared equally. The results indicate a non-equilibrated energy dissipation, and support nucleon exchange based on average single-particle strength functions as the underlying dissipation mechanism at the barrier.
