    Notes: Abstract A refined experimental technique is applied to measure the flux-flow resistance of the strong coupling alloys Pb0.9In0.1, Pb0.8In0.2 and Pb0.7In0.3 and to get the deviations from weak coupling theories. In order to test a theory by Imai devised for arbitrary coupling strengths static quantities entering the flux-flow resistance formulas are calculated using extrapolated tunnel spectra.

    Description / Table of Contents: Zusammenfassung Ein Mann erlitt mit 42 Jahren einen linksseitigen ischämischen Hirninsult mit vorübergehender Aphasie. Mit 49 Jahren erkrankte er durch eine rechtsseitige Infarzierung, die nun eine dauernde Unfähigkeit zum Verstehen gesprochener Sprache und zum Erkennen von Tönen oder Geräuschen hervorrief. Einfache alternative Unterscheidungen zwischen den Reizqualitäten reiner Töne konnte er noch treffen. ERA-Befunde zeigten, daß die zentralen Hörbahnen des Hirnstamms intakt waren. Diese Rindentaubheit im Gefolge bilateraler Läsionen des akustischen Cortex und angrenzender corticaler Zentren führt zu der Annahme, das auditive Erkennen sei beim Menschen beiderseits in den temporoparietalen Regionen repräsentiert.
    Notes: Summary At the age of 42 Lothar H. suffered a left-sided ischaemic brain lesion with transient aphasia, followed at the age of 49 by a right-sided ischemic infarction, which caused a continuous inability to understand spoken language and to identify tones and noises. He was still able to discriminate between single qualities of pure tones. The ERA-results showed the central acoustic pathways of the brain-stem to be intact. The occurrence of cortical deafness following bilateral lesions of the acoustic cortex and adjoining cortical centres supports the view that human auditory recognition is represented in both temporoparietal areas.

    Notes: Abstract Hyperfine structure (hfs) quantum beats of14NII ground terms are observed for the first time after ion beam surface interaction at grazing incidence (IBSIGI). After demonstrating the feasibility of quantum beat measurements of terms (14NII 2p3p3D) directly excited by IBSIGI the transient transfer of orientation to the nucleus after IBSIGI via hyperfine interaction is observed by measuring the circular polarization behind an additional carbon foil positioned perpendicular with respect to the beam axis. The resulting beat-structure is compared with a simulation based on a theoretical description given in this paper and is essentially ascribed to the hfs of the14NII 2s22p2 3P ground state. The applicability of this new method for measuring ionic ground term hfs splittings and some consequences for the interpretation of the IBSIGI interaction are discussed.
