   Sammanfattning : An experiment on elastic scattering of 15 C on 208 Pb at an energy of 65 MeVwas performed at ISOLDE (CERN) exploiting the advantages of the ISOL te-chinique. The measurement showed in increase of the reaction cross section to3035 mb with respect to 12 C, confirming the results obtained at 80 MeV/u. LÄS MER

   Sammanfattning : Palladium complexes have the ability to catalyse cross-coupling of two organic moieties through the formation of transient metal-carbon bonds, thus bringing them closer to each other to facilitate the formation of a new bond. Palladium-catalysed coupling reactions are one of the most important carbon-carbon forming reactions available to organic chemists and many of these reactions rely on the reactivity of aryl-palladium complexes.
