High resolution measurements using the ({sup 3}He,n) reaction are used to determine excitation energies of astrophysically important states. Further, spins can be assigned to these states by comparing the measured differential cross sections to Hauser-Feshbach cross sections. The astrophysical reaction rates are then calculated using ...

The intramolecular rearrangement of 2-(5-cyanotetrazolato)pentaammine cobalt (III) perchlorate (CP) to form the amidine chelate perchlorate coordination complex has been investigated by variable-temperature high-resolution proton nuclear magnetic resonance (NMR) spectroscopy. Using a concentration of 30 wt % CP in perdeuterodimethylsulfoxide ((CD/sub 3/)/sub 2/SO), the ...

The high-resolution x-ray beam position monitor (XBPM) is based on the principle of a segmented longitudinal ionization chamber with integrated readout and USB2 link. In contrast to traditional transversal ionization chambers here the incident x-rays are parallel to the collecting field which allows absolute intensity measurements with a precision better than 0.3 %. ...
In this paper, we survey recent progress in studies of anion formation via (dissociative) electron attachment (DEA) to simple molecules, as measured with the laser photoelectron attachment (LPA) method at high resolution. The limiting (E{yields}0) threshold behavior of the cross sections is elucidated for s-wave and p-wave attachment. Cusps at onsets for ...

Absolute rate coefficients for dielectronic recombination (DR) of H-like U91+ ions have been measured. The electron-ion merged-beam technique at a heavy-ion storage ring was employed using a stochastically cooled ion beam. Thereby, the previously accessible electron-ion collision energies could be greatly extended to the range 63�90 keV. ...
