Absolute elastic differential electron scattering cross sections in the intermediate energy region. IV. CO
Using a crossed electron beam--molecular beam scattering geometry and a relative-flow technique, ratios of elastic differential cross sections of CO to those of He have been measured at electron impact energies of 3, 5, 7.5, 9.9, 15, 20, 30, 50, 75, and 100 eV. At each energy, an angular range of 15/sup 0/ to 130/sup 0/ has been covered. These ratios have been multiplied by previously known He elastic differential cross sections to obtain elastic differential cross sections for CO. Since pure rotational excitations were not resolved, the elastic differential cross sections are a sum of elastic and pure rotational excitations at room temperature. From a knowledge of differential cross sections (DCS), integral and momentum transfer cross sections have been calculated. Both the DCS and integral cross sections are compared at 50, 75, and 100 eV to a recent two-potential theory of e--molecule scattering. Present results show that the isoelectronic molecules CO and N/sub 2/ have very similar magnitudes and shapes of their differential cross sections.
