Abstract

In November 1971 F. Saris, from the FOM Institute in Amsterdam, reported in a seminar talk at Kernforschungsanlage Jülich on his new experimental finding of noncharacteristic x rays from Ar→Ar collisions.1) These noncharacteristic x rays are interpreted in the framework of the electron promotion model2) as radiative transitions between molecular orbitals (MO) in the transiently formed collision molecule. A review of this work is given in this volume by F.J. de Heer, Amsterdam.3) The first experimental results of Saris and coworkers inspired us to look for such noncharacteristic, i. e., quasimolecular x rays for the case of really heavy collision system.4) Additionally, there were suggestions from the theory group of W. Greiner, Frankfurt, to investigate extremely heavy collision systems.5) For such heavy ion-atom collisions — as, e. g., U→U — new features are expected. A review on these new phenomena is given in this volume by W. Greiner.6) As stated there, it is of most interest to look for transitions to the quasimolecular K level in the heaviest collision systems — either radiative transitions or even autoionizing transitions. But until now only radiative transitions in quasimolecules are observed.
