    Notes: The scattering data of a potential, separable in ellipsoidal coordinates, are expanded in perturbed Lamé wave functions. These functions arise when variables in the Schrödinger equation are separated in the ellipsoidal coordinate system. Preliminary calculations are displayed for the total cross section and the scattering amplitude versus direction. The quicker the potential vanishes at infinity the more pronounced is the dependence on the incident direction.   © 1998 John Wiley & Sons, Inc. Int J Quant Chem 70: 1017-1022, 1998

    Partial waves in the nonspherical case (1996)
    New York, NY : Wiley-Blackwell
    International Journal of Quantum Chemistry 60 (1996), S. 1217-1221

    Topics: Chemistry and Pharmacology
    Notes: Many quantum mechanical problems are separable in one or several of the standard classifications of general coordinate systems. The associated solution is most conveniently evaluated using expansions in Lamé wave functions. We give here some preliminary numerical results displaying the continuous distortion of an s-, p-, and d-wave spherical harmonic. The results indicate rather surprising features which may be useful in general quantum mechanical contexts. © 1996 John Wiley & Sons, Inc.

    Scattering by a potential separable in ellipsoidal coordinates (1997)
    New York, NY : Wiley-Blackwell
    International Journal of Quantum Chemistry 65 (1997), S. 601-608 
    Details

    Topics: Chemistry and Pharmacology
    Notes: Some preliminary numerical studies of scattering by a potential separable in a general ellipsoidal coordinate system are presented. The associated scattering or far-field amplitudes are evaluated using expansions in radial and angle Lamé wave functions. Simple representations of the scattering matrix and the far-field amplitude are given as well as some preliminary figures of scattering data and related potential level surfaces.   © 1997 John Wiley & Sons, Inc.
