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, spheri

β¦ Synopsis
Total and differential cross sections for electron elastic scattering by H20 were studied theoretically for collision energies from 2 to 200 eV. The continuum multiple scattering method was applied with the discrete-variable Xa method for determining molecular states. Results of the present study agree reasonably well with measurements and identify the nature of the shape resonance found experimentally at about 10 eV. Our studies show that the backward-scattering cross section is much weaker than that indicated by Brescansin et al. (.I. Chem. Phys. 85

## Nature of physcial problem The scattering of low energy electrons by atoms or ions in the LS coupling scheme, or the rotational or roto-vibrational excitation of diatomic molecules by electron impact in the laboratory frame. ## Restrictions on the complexity of the problem None (see below).
Numerical calculation shows that interference between single scattering and double scattering reduces the independentatom-model cross section by l/3 at 100 eV and l/7 at 5OOeV for Nz and by somewhat larger fractions for P4.
