    Visualization of craters in a Langmuir-Blodgett film from the impact of 23 MeV C60+ ions (1995)

    Notizen: Atomic force microscopy (AFM) images taken from an Fe-arachidate Langmuir-Blodgett film irradiated with 23 MeV fullerene ions gives clear evidence that craters are formed as a result of the cluster-ion impact. The crater diameter fits into a systematic formula already found for atomic ions. The AFM images indicate that even the largest molecular ions desorbed stem from the crater volume.

    Notizen: In Part I a detailed derivation of a more general shallow water equation set was developed via a perturbation analysis. A finite element computational model of these more general equations is now constructed and the model behavior is compared with conventional shallow water formulations applied to an outletworks flume. © 1998 John Wiley & Sons, Ltd.

    Free-surface flow over curved surfaces: Part I: Perturbation analysis (1998)

    Notizen: The standard two-dimensional shallow water equation formulation assumes a mild bed slope and no curvature effect. These assumptions limit the applicability of these equations for some important classes of problems. In particular, flow over a spillway is affected by the bed curvature via a decidedly non-hydrostatic pressure distribution. A detailed derivation of a more general equation set is given here in Part I. The method relies upon a perturbation expansion to simplify a bed-fitted co-ordinate configuration of the three-dimensional Euler equations. The resulting equations are essentially the equivalent of the two-dimensional shallow water equations but with curvature included and without the mild slope assumption. A finite element analysis and flume result are given in Part II. © 1998 John Wiley & Sons, Ltd.

    Algorithms for exact counting of energy levels of spectroscopic transitions at different temperatures (1997)
    New York, NY [u.a.] : Wiley-Blackwell

    Notizen: The KDB energy level counting algorithm [M. J. H. Kemper, J. M. F. Van Dijk, and H. M. Buck, Chem. Phys. Lett., 53, 21 (1978)] has been modified such as to generate simultaneously the internal energy levels in two different states. Such algorithms are necessary for a description of the temperature dependence of the rotovibronic fine structure of electronic transitions as well as the rotatory fine structure of vibrational spectra. The performance of two versions of the algorithms as well as extensions to restrict the generation scheme to selected modes are discussed. © 1997 John Wiley & Sons, Inc.   J Comput Chem 18: 1312-1319, 1997
