    Notes: Abstract We report the first observation of the doubly-magic nucleus100Sn. This isotope was produced by nuclear fragmentation of124Xe projectiles at 1095 A·MeV using the heavy-ion synchrotron SIS at GSI, Darmstadt. The projectile fragments were separated in flight with the projectile-fragment separator FRS and identified by measuring event by event the magnetic rigidity, the time of flight and the energy deposition.

    Description / Table of Contents: Zusammenfassung. Von 63 Patienten, welche eine tiefe anteriore Rectumresektion erhielten, wurden 39 mit einer direkten coloanalen Anastomose (CAA), 24 unter Zwischenschaltung eine Colon-J-Pouches als colonpouchanale Anastomose (CPA) rekonstruiert. Lokalseptische Komplikationen traten in 20,5 % aller Patienten nach CAA gegenüber 12,5 % nach CPA auf, die Stuhlfrequenz war nach zusätzlicher Pouchanlage 3,3 pro 24 h verglichen mit 5,2 pro 24 Std nach direkter coloanaler Anastomose (p = 0,053). Die postoperative Kontinenz war in der Pouchgruppe tendentiell besser (n. s.), die Analmanometrie zeigte lediglich einen signifikanten postoperativen Abfall des Ruhedruckes nach direkter coloanaler Anastomose. Die Ergebnisse sprechen für die Anlage eines primären Colonpouches, da die lokalseptische Komplikationsrate nach colonpouchanaler Anastomose niedriger und das funktionelle Ergebnis tendentiell günstiger ist.
    Notes: Summary. Thirty-nine of 63 patients undergoing deep anterior rectal resection received a straight coloanal anastomosis (CAA); the remaining 24 patients additionally had a colon-j-pouch (CPA) constructed. After pouch-anal anastomosis, local septic complications occurred in 12.5 % of patients compared to 20.5 % after coloanal anastomosis. Stool frequency after pouch-anal anastomosis was 3.3 per 24 h compared to 5.2 per 24 h after straight anastomosis within the first year after ileostomy closure (P = 0.053). Continence was slightly better in the pouch group (n. s.), and anal manometry showed a significant postoperative decrease only in resting pressure after straight coloanal anastomosis (P 〈 0.001). This study supports the construction of a colon-j-pouch after deep rectal resection, as the pouch-anal anastomosis has fewer local septic complications and seems to improve functional outcome.

    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.
