    2 1S excitation of helium: A precise distorted wave approach (1985)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The differential and total cross sections are evaluated for 1 1S–2 1S excitation of helium atom by electron impact in distorted wave approximation. The effect of the distortion of incident electron, contribution due to polarization of target and the exchange effect are appropriately taken in both the initial and final channels. Fourier decomposition of interaction potential between the projectile and target is taken and an accurate form factor has been used to calculate the transition matrix. The present results are compared with various distorted wave models as well as other theoretical and experimental results.

    Scattering of high-energy electrons and x-rays from molecules: The 10-electon series Ne, HF, H2O, NH3, and Ch4 (1986)
    New York, NY : Wiley-Blackwell
    International Journal of Quantum Chemistry 29 (1986), S. 1339-1349 
    Details
    ISSN: 0020-7608

    Topics: Chemistry and Pharmacology
    Notes: The elastic, inelastic, and total intensities for x-ray and high-energy electron scattering from the 10-electron systems Ne, HF, H2O, NH3, and CH4 have been calculated by using SCF-MO wave functions obtained with double-zeta quality bases of Gaussian contractd wave functions. The effect of molecular binding and various other trends and systematics in the intensities have been examined with the help of difference functions computed between the present scattering intensities and those for the indpendent atom model (IAM).

    Scattering of fast electrons and X-rays from CO2 molecules (1987)
    New York, NY : Wiley-Blackwell
    International Journal of Quantum Chemistry 32 (1987), S. 217-227 
    Details
    ISSN: 0020-7608
    Keywords: Computational Chemistry and Molecular Modeling ; Atomic, Molecular and Optical Physics
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Self-consistent field (SCF) wave functions for CO2 are used to calculate cross sections for the elastic and inelastic scattering of fast electrons and x-rays from CO2 molecules. The effects of basis set choice and free rotation on these cross sections are investigated. The utility of an approximate scheme to correct SCF inelastic cross sections for the effects of electron correlation is examined. The probability density for the interelectronic distance, or radial intracule density, is obtained as a by-product.
