• Steric effects in chemiluminescent reactions of metastable Ca∗, Sr∗ atoms with isomeric propyl halides
  作者：B. Pranszke、P. Kierzkowski、A. Kowalski

  Reactions of metastable alkaline earth atoms with normal and branched propyl halides were studied in a beam-gas arrangement. Chemiluminescence spectra of alkaline earth monohalides were observed for calcium and strontium reactions. Some differences in the CaX () branching ratio were found with isomeric variation of the targets. Total collision cross-sections for Mg∗ and Ca∗ reactions are independent

  The lifetimes of the A2Π, B2Σ+, C2Π and D2Σ+ states of the CaBr and CaI radicals have been measured directly from the time rate of fluorescence decay using an appropriate pulsed dye laser as an excitation source. The zero pressure radiative lifetimes determined for the first time for the C2Π1/2 state of CaI and D2Σ+ state of CaBr were (50.5 ± 1.5) ns and (21.0 ± 2.6) ns, respectively. The measured

• State selective reactions prepared through the excitation of orbital states in van der Waals complexes of Ca–HX*

  We have observed the chemiluminescent reaction Ca*+HX→CaX*+H, where the reactants are prepared in a van der Waals complex formed in a supersonic expansion. This preparation, combined with tunable laser excitation, allows access to well-defined electronic states of the reaction complex corresponding to different orientations of the calcium excited orbital. In the case of the Ca–HBr complex, a remarkable effect of this preparation is observed on the branching ratio to the final excited states A 2Π and B 2Σ of CaBr: Depending upon the selected state of the complex, the A/B ratio varies by a factor of 2. This is interpreted by the conservation of the orbital orientation during the reaction involving the departure of the hydrogen.

• Hyperfine and spin–rotational structure of CaBr X ²Σ (v = 0) by molecular‐beam laser‐rf double resonance

  The molecular-beam, laser–rf, double-resonance technique has been used to make high-precision measurements of the spin–rotation and hyperfine interactions in the X 2Σ (v = 0) electronic ground state of Ca79Br and Ca81Br. The spin–rotation interaction is found to have a strong N dependence. The Frosch–Foley magnetic hyperfine parameters b and c and the electric–quadrupole hfs parameter eqQ are determined for both molecules.
