    Notes: Reactions with a heavy projectile incident on a light target can be used for the efficient in-flight production of secondary radioactive beams. An overview of this technique is given using data on 17F beams produced via the p(17O, 17F)n and d(16O, 17F)n reactions. With primary 16,17O beam currents of 100 pnA, intensities of up to 2×106 17F/s on target were achieved. Using this beam, the p(17F,α)14O reaction was measured. © 2000 American Institute of Physics.

    Notes: Abstract Mass and charge transfer was investigated for the system136Xe+208Pb at 5.9 MeV/nucleon incident energy with aΔE —E-time of flight telescope. The angle and energy integrated cross section for the strongly damped events was found to be 510 mb, very close to the total reaction cross section. The width of the mass distribution as function of the total kinetic energy loss was measured and is compared to the width of the corresponding charge distribution. An upper limit of 1 μb has been found for processes with very large mass transfer.

    Notes: Abstract Investigation of the system32S+48Ca at 125 MeV incident energy reveals that “exotic” reactions, like the 4p-transfer (32S,28Mg) and the double charge exchange (32S,32Si) occur with large cross sections of 0.23 mb and 2.7 mb, respectively.

    Notes: Abstract The fragmentation of the total reaction cross section was investigated for16O +208Pb atE c.m.=84 MeV andE c.m.=92 MeV. Total cross sections for the inelastic, transfer and fission channels were measured. The sum of the inelastic and transfer channels accounts for 30% of the total reaction cross section; the residual strength is found in a compoundfission process.

    Notes: Abstract The production of superheavy elements in binary reactions of the type208Pb (136Xe, X) Y was investigated atE c.m.=470 MeV. The experiment was designed to search for delayed fission products from elements withZ between 108 and 116 and fission lifetimes ofΤ≳10−12 s. No fission events were observed the upper limit for the formation cross section being 1.2 Μbarn.

    Notes: Abstract The energy dependence of the one- and two-particle transfer reactions90Zr(16O,17O)89Zr,90Zr(16O,15N)91Nb and90Zr(16O,14C)92Mo was studied at bombarding energies of 80MeV, 138.2 MeV and 194.4 MeV. A comparison with one-step DWBA calculations shows good agreement for the one-particle transfers over the whole energy range. For the two-proton transfer reaction (16O,14C) the discrepancies between experiment and theory are large with an exponential decrease towards higher energies. Current theories are unable to describe this behavior.

    Notes: Abstract An anatomic study of the lateral extraosseous and intraosseous arterial supply of the calcaneus and the lateral soft tissue was carried out on 10 fresh lower adult cadaver legs using different anatomic and radiologic procedures (plastination, modified Spalteholz clearing technique, digital subtraction and rotational angiography and computed tomographic angiography). Consistent patterns of extraosseous and intraosseous lateral calcaneal vascular anatomy were demonstrated. The lateral calcaneal artery is a branch of the anterior tibial artery which crosses over the calcaneal tuberosity and forms a large lateral arch with the lateral tarsal artery which is a branch of the dorsalis pedis artery. The intraosseous circulation is supplied laterally by the lateral calcanear artery, medially via the short branches of the lateral plantar artery. Comparing magnet resonance images after fresh calcaneal fractures the lateral calcanear artery may be interrupted by the impacted lateral bulge, by the conventional lateral surgical approach, or by applying a lateral osteosynthesis plate. This may cause avascular bone necrosis. Furthermore the lateral calcanear artery can clinically serve as a vascular pedicle for a local rotational skin flap to cover soft tissue defects of the heel.

    Description / Table of Contents: Résumé L'étude anatomique de la vascularisaiton artérielle extra et intraosseuse du calcanéus et des parties molles a été faite sur 10 jambes fraîches de cadavres d'adultes. Différentes techniques anatomiques et radiologiques ont été utilisées : plastination, diaphanisation (technique de Spaltholtz modifiée), angiographie numérisée par soustraction, angiographie rotationnelle et angiographie par tomographie computérisée. Les aspects habituels de l'anatomie vasculaire de la région latérale du calcanéus ont été décrits : l'ACL est un rameau de l'artère tibiale postérieure ; elle surcroise la tubérosité calcanéenne et constitue une large arcade latérale avec l'artère tarsienne latérale, branche de l'artère dorsale du pied. La moitié de la circulation intraosseuse passe par l'ACL, médialement par des rameaux courts de l'artère plantaire latérale. Lorsqu'on examine les images obtenues en IRM lors de fractures récentes du calcanéus, on constate que l'ACL risque d'être lésée par l'élargissement latéral du calcanéus écrasé. Elle peut l'être aussi lors de l'abord latéral classique de l'os ou lors de l'application d'une plaque d'ostéosynthèse. Le risque en est la nécrose ischémique de l'os. Enfin, l'ACL peut constituer un pédicule vasculaire intéressant pour un lambeau local de rotation, lors de la couverture des pertes de substances cutanées du talon.
