Abstract
Scattering of KI by 0.81–15.7 eV electrons has been observed using the molecular beam recoil technique. Center of mass cross section models are adjusted to fit the apparatus space scattering pattern. Absolute total cross sections agree at high energies with the first Born approximation and are a factor of 4 smaller at the lowest energy. At low energies the momentum transfer cross sections are an order of magnitude below theory. The measured cross sections are nominally identical to those measured in CsCl.
