Abstract
Utilising the crossed electron-beam-molecular-beam scattering technique, relative values of differential 'elastic' cross sections sigma ( theta ) have been measured at electron impact energies of 5.4 and 20 eV for the angular range 20 degrees to 130 degrees . The absolute values of these cross sections have been obtained by normalisation to the classical perturbation theory of Dickinson (1977) at 40 degrees scattering angle. These differential cross sections have then been used to calculate the integral and momentum-transfer cross sections. An energy-loss spectrum at 100 eV electron impact energy and 15 degrees scattering angle has also been obtained. Two weak features at the energy losses of 6.74 and 8.82 eV appear. Their energy positions are compared with the recent calculations of Kahn et al. (1974).Keywords
