    Description / Table of Contents: Zusammenfassung Die Reißkraft und Reißfestigkeit excidierter Rückenhautstreifen von unterschiedlich alten Ratten wurde nach dreiwöchiger oraler Behandlung mit 320 mg/kg/died-Penicillamin vergleichend geprüft. Die durch die Behandlung mit d-Penicillamin verursachte relative Abnahme von Reißkraft und Reißfestigkeit exzidierter Rückenhautstreifen hängt vom Alter der Ratten ab: Je jünger die Tiere zum Zeitpunkt des Behandlungsbeginns sind, desto größer ist die relative Abnahme von Reißkraft und Reißfestigkeit.
    Notes: Summary Load resulting in rupture and tensile strength of excised strips of dorsal skin in rats of different age after a 3 week treatment withd-penicillamine (320 mg/kg) have been comparatively tested. The relative decrease of load resulting in rupture and tensile strength of the strips of dorsal skin induced by treatment withd-penicillamine depends on the age of the rats: the relative decrease of load resulting in rupture and tensile strength is more pronounced the younger the animals are when the treatment is started.

    Die Erzeugung von negativen polarisierten Deuteriumionen aus metastabilen Deuteriumatomen im 2S 1/2-Zustand (1969)

    Notes: Abstract An experimental method to produce polarized negative hydrogen ions is discussed and compared with other methods. The method makes use of the different lifetimes of the metastable 2S 1/2 state and the 2P 1/2 state of the hydrogen atom. Polarized ion beams are obtained by using a selective quenching process followed by selective ionisation. Experimental results are given for the intensity and polarization of the polarized negative ion beam of deuterons. These results were obtained as a function of the quenching-field, the magnetic field in the argon-cell and the density of argon and cesium. The yield of negative ions can be expressed by the cross sections for the different charge exchange reactions in argon. The measured tensorpolarisationP 33 can be interpreted as a function of the cross sections, the argon-density and the magnetic field along the beam axis. Beams of 50 nA intensity were produced with a polarization ofP 33=−0.250±0.006. The main advantage of this method is a low beam emittance, values of 0.7 cm rad eV1/2 were achieved. The production of a polarized positive deuteron beam seems to be possible.

    Umbesetzung der 2S 1/2-Hyperfeinstrukturniveaus im metastabilen Deuteriumatomstrahl einer Lambshift-Quelle durch Anwendung von statischen Magnetfeldern (1970)

    Notes: Abstract Polarized deuteron beams may be obtained from metastable atomic beams by quenching three of the six hyperfinestructure levels. Using a field distribution which crosses zero on the beam axis the occupation numbers of the hyperfinestructure levels may be changed by a nonadiabatic process. The special conditions for this magnetic field are discussed by comparing the corresponding Larmor frequency of the metastable atoms with the angular frequency of the magnetic field vector. Experimental investigations were carried out for field gradients between 1.9 and 5.4 Oe/cm and for superposed homogeneous transverse fields of up to 6 Oe. With deuterons a tensorpolarization ofP 33=−0.70±0.01 was obtained at a negative ion beam current of 42 nA.
