    Spontaneous emission in the near-resonant kapitza-dirac effect (1992)
    Springer
    Applied physics 54 (1992), S. 451-466

    Notes: Abstract We study the influence of spontaneous emission on atom diffraction by a standing wave laser field. We characterize, analytically, the major regimes of the near-resonant Kapitza-Dirac effect and study, numerically, the influence of spontaneous emission. In particular, we discuss in some detail two important classes of two-beam resonances which are major candidates to develop effective atom beam splitters, the so-called Bragg and Doppleron resonances.

    On ionisation induced unimolecular dissociation of sodium clusters (1987)
    Springer

    Notes: Abstract Fragmentation of sodium cluster ions (Na x + ,x〈42) was studied via photoionisation of neutral precursors. Expansions of metal vapor out of cylindrical and conical nozzles yielded supersonic beams with differing cluster compositions. Measurements of photoionisation efficiency curves in the 3–6 eV range for both types of expansion allow quantitative separation of direct ionisation and unimolecular dissociation contributions to specific ion signals. Data for Na 8 + and Na 7 + are analysed to yield lower limits on bond energies. Results obtained for larger clusters are also discussed.
