Laser-induced multiphoton dissociation ofn-butyl ether

The pulsed CO₂-laser-induced multiphoton dissociation of n-butyl vinyl ether is studied. Comprehensive measurements have been performed for 9.6.μm and 10.6 μm irradiation. The corresponding dissociation product distributions show distinct differences for the two irradiation wavelengths, the most important finding being that acetylene is only produced at 9.6 μm.     

Reactions of polynuclear complexes novel benzotriazole-allylamine cobalt complexes and their oxidizing properties

The absorption of oxygen by solutions of bis(triphenylphosphine)cobalt(II) chloride in allylamine in the presence of heterocyclic ligands has been studied. Novel complexes are formed in the presence of benzotriazole. A new class of trinuclear complexes has been discovered and studied by X-ray diffraction. Oxidation of triphenylphosphine takes place catalytically in the presence of oxygen under mild conditions.

Relative line intensities in the argon L x-ray emission spectra produced by 0.3 to 3 keV electron impact

This note presents the first measurement of the relative intensities of the radiative processes of the L shell of argon. The partial emission cross sections are deduced. Our data show that the radiative transitions within the excited ion are very sensitive to the incident electron energy.     

Lifetimes of high-spin yrast states in 154Er

Lifetimes for high-spin levels (between about 10 and 30 ?) in ¹⁵⁴Er have been measured by the recoil-distance method. Non-collective, moderately collective and collective E2 transitions from states with lifetimes between at most 10 and 400 ps have been found. All available data on this nucleus are discussed within the framework of the oblate coupling scheme with the addition of collective degrees of freedom.     

Interaction of domain walls in thin magnetic films

Interactions of pairs of parallel Néel walls are investigated by means of Ritz's method calculations. In the case of the symmetric, thin-film mode of Néel walls, unwinding walls show an attractive and winding walls a repulsive interaction for all distances. The functional dependence of the interaction on the distance of the walls is strongly correlated with the wall profiles of the isolated walls with their characteristic extended tails. For the asymmetric Néel wall mode which occurs in thicker films, an additional repulsive interaction of the magnetization vortices in the wall core is found. This leads for unwinding walls to stable configurations of double walls with separations between two and three times the film thickness.
