✦ Synopsis
We report the first calculations on the differential, integral and momentum transfer cross sections for electron scattering with germane (GeH.,) molecules in the energy range of l-100 eV, where results are compared with recent measurements of angular distributions. We employ a parameter-free, spherical effective potential approach in which the static, exchange and polarization terms are determined from the target charge density that is in turn evaluated from a multicenter near-Hartree-Fock GeH, wavefunction. Our cross sections compare very well with the measured data, particularly above 10 eV where the present scattering treatment is most likely to be valid. There is a shape resonance feature around 5 eV present both in the measured and the theorctical cross sections.
