    Notes: Abstract A detailed level scheme for179Hf has been constructed on the basis of extensive (n, γ), (d, p) and (d, t) data. The low lying levels are grouped into 15 rotational bands of which 14 are classified by Nilsson quantum numbers or vibrational configurations. One of the most interesting results concerns a dominant transition matrix element which connects an octupole vibration built on the 1/2[510] Nilsson orbit with a quadrupole vibration built on the 9/2+ [624] Nilsson ground state. A simple interpretation of this unusual decay mode is offered in terms of microscopic wave functions for the vibrational states. This interpretation leads to reasonable estimates forE1 hindrance factors from the octupole vibration to lower lying quasi-particle levels.

    The effect of the electron spin on angular momentum transfer in Na*(32 P 3/2)+Na+ collisions — crossed beam experiment and semiclassical calculation (1986)
    Springer

    Notes: Abstract The angular momentum transfer between electronic and heavy particle motion has been studied for inelastic collisions of laser state-prepared Na*(32 P 3/2,M J ) with Na+ leading to Na*(32 D) or Na(32 S) in the energy rangeE cm=5−47.5 eV. The measurements are compared to semiclassical calculations employing the coupled channel method in the impact parameter approximation but including dynamics of the electron spin coupling to the heavy particle motion.

    Description / Table of Contents: Neue Prophosphatrane: Neuartige Zwischenstufen auf dem Wege zu pentakoordinierten PhosphatranenDie Reaktion von N(CH2CH2NHMe)3 mit P(NMe2)3 oder P(NMe2)2Cl ergibt die Phosphatranvorstufe N(CH2CH2NMe)3P. Dessen Umsetzung mit Oxydationsmitteln ode Elektrophilen führt zu nicht-transannular-stabilisierten, tetrakoordinierten Derivaten N(CH2CH2NMe)3P—X, (X: O, S, Se, N3Ph, NPh, CS2, 1/2 PtCl2). Die Strukturen der beschriebenen Verbindungen werden anhand ihrer 1H-, 13C- und 31P-NMR-Daten diskutiert.

    Description / Table of Contents: Cycloaddition of Dithiocyanogen and Trithiocyanogen with Hexafluoroacetone and Products of the Cleavage of the Sulfur-Sulfur Bond in Dithiocyan-Hexafluoroacetone Adduct by Elemental ChlorineThe reaction of dithiocyanogen and trithiocyanogen with hexafluoroacetone (HFA) leads to the cycloaddition products (SCN)2 · 4 HFA 1 and S(SCN)2 · 4 HFA 2. These are the first reactions of (SCN)2 and S(SCN)2 without cleavage of the S - S bonds. Elemental chlorine cleaves in 1 the S—S bond and 3 is formed. In 3 the chlorine atom can be replaced by the rests  - CN 4, (C6H11)2N -  5, and n-C4H9- 6. 6 eliminates one molecule of HFA by warming up and the four-membered ring 7 is formed. The compounds were characterized on the basis of mass and nmr spectra.
    Notes: Die Reaktion von Dithiocyan und Trithiocyan mit Hexafluoraceton (HFA) führt zu den Cycloadditionsprodukten (SCN)2 · 4 HFA 1 und S(SCN)2 · 4 HFA 2. Es sind die ersten Reaktionen des (SCN)2 und S(SCN)2, die nicht unter Spaltung der S—S-Bindungen verlaufen. Durch elementares Chlor wird 1 an der S—S-Bindung gespalten und es entsteht 3. In 3 kann das Chloratom durch die Reste  - CN 4, (C6H11)2N -  5 und n-C4H9- 6 ersetzt werden. Beim Erwärmen verliert 6 ein Molekül HFA und es entsteht der viergliedrige Ring 7. Die Verbindungen wurden anhand ihrer Massen- und NMR-Spektren eindeutig charakterisiert.
